Subject: stmmac: enable rx queues

When the hardware is synthesized with multiple queues, all queues are
disabled for default. This patch adds the rx queues configuration.
This patch was successfully tested in a Synopsys QoS Reference design.

Subject: bnxt_en: Improve the IRQ disable sequence during shutdown.

The IRQ is disabled by writing to the completion ring doorbell.  This
should be done before the hardware completion ring is freed for correctness.
The current code disables IRQs after all the completion rings are freed.

Fix it by calling bnxt_disable_int_sync() before freeing the completion
rings.  Rearrange the code to avoid forward declaration.

Subject: bnxt_en: Fix and clarify link_info->advertising.

The advertising field is closely related to the auto_link_speeds field.
The former is the user setting while the latter is the firmware setting.
Both should be u16.  We should use the advertising field in
bnxt_get_link_ksettings because the auto_link_speeds field may not
be updated with the latest from the firmware yet.

Subject: bnxt_en: Add new hardware RFS mode.

The existing hardware RFS mode uses one hardware RSS context block
per ring just to calculate the RSS hash.  This is very wasteful and
prevents VF functions from using it.  The new hardware mode shares
the same hardware RSS context for RSS placement and RFS steering.
This allows VFs to enable RFS.

Subject: bnxt_en: Implement new scheme to reserve tx rings.

In order to properly support TX rate limiting in SRIOV VF functions or
NPAR functions, firmware needs better control over tx ring allocations.
The new scheme requires the driver to reserve the number of tx rings
and to query to see if the requested number of tx rings is reserved.
The driver will use the new scheme when the firmware interface spec is
1.6.1 or newer.

Subject: bnxt_en: Set default completion ring for async events.

With the added support for the bnxt_re RDMA driver, both drivers can be
allocating completion rings in any order.  The firmware does not know
which completion ring should be receiving async events.  Add an
extra step to tell firmware the completion ring number for receiving
async events after bnxt_en allocates the completion rings.

Subject: bnxt_en: Handle no aggregation ring gracefully.

The current code assumes that we will always have at least 2 rx rings, 1
will be used as an aggregation ring for TPA and jumbo page placements.
However, it is possible, especially on a VF, that there is only 1 rx
ring available.  In this scenario, the current code will fail to initialize.
To handle it, we need to properly set up only 1 ring without aggregation.
Set a new flag BNXT_FLAG_NO_AGG_RINGS for this condition and add logic to
set up the chip to place RX data linearly into a single buffer per packet.

Subject: liquidio: optimize reads from Octeon PCI console

Reads from Octeon PCI console are inefficient because before each read
operation, a dynamic mapping to Octeon DRAM is set up.  This patch replaces
the repeated setup of a dynamic mapping with a one-time setup of a static
mapping.

Subject: net: 3com: typhoon: typhoon_init_one: fix incorrect return values

In a few cases the err-variable is not set to a negative error code if a
function call in typhoon_init_one() fails and thus 0 is returned
instead.
It may be better to set err to the appropriate negative error
code before returning.

Subject: qed*: Update to dual-license

Since the submission of the qedr driver, there's inconsistency
in the licensing of the various qed/qede files - some are GPLv2
and some are dual-license.
Since qedr requires dual-license and it's dependent on both,
we're updating the licensing of all qed/qede source files.

Subject: qed*: Change maximal number of queues

Today qede requests contexts that would suffice for 64 'whole'
combined queues [192 meant for 64 rx, tx and xdp tx queues],
but registers netdev and limits the number of queues based on
information received by qed. In turn, qed doesn't take context
into account when informing qede how many queues it can support.

This would lead to a configuration problem in case user tries
configuring >64 combined queues to interface [or >96 in case
xdp isn't enabled]. Since we don't have a mangement firware
that actually provides so many interrupt lines to a single
device we're currently safe but that's about to change soon.

The new maximum is hence changed:
  - For RoCE devices, the limit would remain 64.
  - For non-RoCE devices, the limit might be higher [depending
    on the actual configuration of the device].
qed would start enforcing that limit in both scenarios.

Subject: qede: Postpone reallocation until NAPI end

During Rx flow driver allocates a replacement buffer each time
it consumes an Rx buffer. Failing to do so, it would consume the
currently processed buffer and re-post it on the ring.
As a result, the Rx ring is always completely full [from driver POV].

We now allow the Rx ring to shorten by doing the re-allocations
at the end of the NAPI run. The only limitation is that we still want to
make sure each time we reallocate that we'd still have sufficient
elements in the Rx ring to guarantee that FW would be able to post
additional data and trigger an interrupt.

in firmware/hardware - let the RSS indirections use queue handles
instead of actual queue indices.

Subject: net: stmmac: remove unused duplicate property snps,axi_all

For core revision 3.x Address-Aligned Beats is available in two registers.
The DT property snps,aal was created for AAL in the DMA bus register,
which is a read/write bit.
The DT property snps,axi_all was created for AXI_AAL in the AXI bus mode
register, which is a read only bit that reflects the value of AAL in the
DMA bus register.

Since the value of snps,axi_all is never used in the driver,
and since the property was created for a bit that is read only,
it should be safe to remove the property.

Subject: IB/mlx5: Refactor UMR post send format

* Update struct mlx5_wqe_umr_ctrl_seg.
* Currenlty UMR send_flags aim only certain use cases: enabled/disable
  cached MR, modifying XLT for ODP. By making flags independent make UMR
  more flexible allowing arbitrary manipulations.
* Since different UMR formats have different entry sizes UMR request
  should receive exact size of translation table update instead of
  number of entries. Rename field npages to xlt_size in struct mlx5_umr_wr
  and update relevant code accordingly.
* Add support of length64 bit.

From 7d0cc6edcc7011133c45f62a7796a98b8cb5da0f Mon Sep 17 00:00:00 2001
From: Artemy Kovalyov <artemyko@mellanox.com>
Date: Mon, 2 Jan 2017 11:37:44 +0200
Subject: IB/mlx5: Add MR cache for large UMR regions

In this change we turn mlx5_ib_update_mtt() into generic
mlx5_ib_update_xlt() to perfrom HCA translation table modifiactions
supporting both atomic and process contexts and not limited by number
of modified entries.
Using this function we increase preallocated MRs up to 16GB.

Subject: net/mlx5: Update PAGE_FAULT_RESUME layout

Update PAGE_FAULT_RESUME command layout.

Three bit fields describing page fault: rdma, rdma_write, req_res gave 8
possible combinations, while only a few were legal. Now they
are interpreted as three-bit type field, where former legal
combinations turns into corresponding types and unused were added as new
types.

Subject: {net,IB}/mlx5: Refactor page fault handling

* Update page fault event according to last specification.
* Separate code path for page fault EQ, completion EQ and async EQ.
* Move page fault handling work queue from mlx5_ib static variable
  into mlx5_core page fault EQ.
* Allocate memory to store ODP event dynamically as the
  events arrive, since in atomic context - use mempool.
* Make mlx5_ib page fault handler run in process context.

From: Philippe Reynes <tremyfr@gmail.com>
Date: Sun, 1 Jan 2017 19:05:38 +0100
Subject: net: dec: de2104x: use new api ethtool_{get|set}_link_ksettings

The ethtool api {get|set}_settings is deprecated.
We move this driver to new api {get|set}_link_ksettings.

Subject: net: dlink: dl2k: use new api ethtool_{get|set}_link_ksettings

The ethtool api {get|set}_settings is deprecated.
We move this driver to new api {get|set}_link_ksettings.

The previous implementation of set_settings was modifying
the value of speed and duplex, but with the new API, it's not
possible. The structure ethtool_link_ksettings is defined
as const.

Subject: ixgbe: Fix check for ixgbe_phy_x550em_ext_t reset

The generic PHY reset check we had previously is not sufficient for the
ixgbe_phy_x550em_ext_t PHY type.  Check 1.CC02.0 instead - same as
ixgbe_init_ext_t_x550().

Subject: ixgbe: Reduce I2C retry count on X550 devices

A retry count of 10 is likely to run into problems on X550 devices that
have to detect and reset unresponsive CS4227 devices. So, reduce the I2C
retry count to 3 for X550 and above. This should avoid any possible
regressions in existing devices.

Subject: ixgbe: handle close/suspend race with netif_device_detach/present

When an interface is part of a namespace it is possible that
ixgbe_close() may be called while __ixgbe_shutdown() is running
which ends up in a double free WARN and/or a BUG in free_msi_irqs().

To handle this situation we extend the rtnl_lock() to protect the
call to netif_device_detach() and ixgbe_clear_interrupt_scheme()
in __ixgbe_shutdown() and check for netif_device_present()
to avoid clearing the interrupts second time in ixgbe_close();

Also extend the rtnl lock in ixgbe_resume() to netif_device_attach().

To handle this situation we extend the rtnl_lock() to protect the

Subject: ixgbe: test for trust in macvlan adjustments for VF

There are two methods for setting mac addresses in a Macvlan, that
differentiate themselves in the function macvlan_set_mac_Address.
If the macvlan mode is passthru, then we use the dev_set_mac_address
method, otherwise we use the dev_uc api via macvlan_sync_addresses.
The latter method (which would stem from using any non-passthru mode,
like bridge, or vepa), calls down into the driver in a path that terminates
in ixgbevf_set_uc_addr_vf, which sends a IXGBE_VF_SET_MACVLAN message,
which causes the pf to spawn the noted error message.  This occurs because
it appears that the guest is trying to delete the mac address of the macvlan
before adding another.

The other path in macvlan_set_mac_address uses dev_set_mac_address, which
calls into ixgbevf_set_mac which uses the IXGBE_VF_SET_MAC_ADDR to the
pf to set the macvlan mac address.

The discrepancy here is in the handlers.  The handler function for
IXGBE_VF_SET_MAC_ADDR (ixgbe_set_vf_mac_addr) has a check for
the vfinfo[].trusted bit to allow the operation if the vf is trusted.
In comparison, the IXGBE_VF_SET_MACVLAN message handler
(ixgbe_set_vf_macvlan_msg) has no such check of the trusted bit.

Subject: ixgbe: fix AER error handling

Make sure that we free the IRQs in ixgbe_io_error_detected() when
responding to an PCIe AER error and also restore them when the
interface recovers from it.

Previously it was possible to trigger BUG_ON() check in free_msix_irqs()
in the case where we call ixgbe_remove() after a failed recovery from
AER error because the interrupts were not freed.

Subject: ixgbe: Fix incorrect bitwise operations of PTP Rx timestamp flags

Rx timestamp does not work on 82599 and X540 because bitwise operation
of RX_HWTSTAMP flags is incorrect and ixgbe_ptp_rx_hwtstamp() is never
called. This patch fixes it to enable Rx timestamp on 82599 and X540.

Without this fix:
ptp4l[278.730]: selected /dev/ptp8 as PTP clock
ptp4l[278.733]: port 1: INITIALIZING to LISTENING on INITIALIZE

Subject: ixgbe: Fix issues with EEPROM access

There are two problems with EEPROM access. One is that it needs to
hold the semaphore until the entire response is read or else the
response can be corrupted by other firmware accesses. The second
problem is that acquiring and releasing the semaphore is slow, so
it should be taken and released once when multiple EEPROM accesses
will be done.

Both of these issues can be solved by adding a new function,
ixgbe_hic_unlocked, to issue firmware commands that will assume
that the caller has acquired the needed semaphore.

Subject: ixgbe: Add PF support for VF promiscuous mode

This patch extends the xcast mailbox message to include support for
unicast promiscuous mode.  To allow a VF to enter this mode the PF
must be in promiscuous mode.

A later patch will add the support needed in the VF driver (ixgbevf)

Subject: liquidio: remove PTP support in 23XX adapters

liquidio driver incorrectly indicates that PTP is supported in 23XX
adapters; this patch fixes that.  PTP is supported in 66XX and 68XX
adapters, and the driver correctly indicates that.

Subject: sh_eth: handle only enabled E-MAC interrupts

The driver should only handle the enabled E-MAC interrupts, like it does
for the E-DMAC interrupts since commit 3893b27345ac ("sh_eth: workaround
for spurious ECI interrupt"),  so mask ECSR with  ECSIPR when reading it
in sh_eth_error().

Subject: sh_eth: no need for *else* after *goto*

Well, checkpatch.pl complains about *else* after *return* and *break* but
not after *goto*... and it probably should have complained about the code
in sh_eth_error().  Win couple LoCs by removing that *else*. :-)

Subject: sh_eth: factor out sh_eth_emac_interrupt()

The E-MAC interrupt (EESR.ECI) is not always caused  by an error condition,
so  it really shouldn't be handled by sh_eth_error(). Factor out the E-MAC
interrupt handler, sh_eth_emac_interrupt(),  removing the ECI bit from the
EESR's values throughout the driver...

Update Cogent Embedded's copyright and clean up the whitespace in Renesas'
copyright, while at it...

Subject: net: xilinx: emaclite: Remove xemaclite_remove_ndev()

xemaclite_remove_ndev() is a simple wrapper around free_netdev()
checking for NULL before the call. All possible paths calling
it are guaranteed to pass a non-NULL argument, so rather call
free_netdev() directly.

Subject: e1000e: driver trying to free already-free irq

During systemd reboot sequence network driver interface is shutdown
by e1000_close. The PCI driver interface is shut by e1000_shutdown.
The e1000_shutdown checks for netif_running status, if still up it
brings down driver. But it disables msi outside of this if statement,
regardless of netif status. All this is OK when e1000_close happens
after shutdown. However, by default, everything in systemd is done
in parallel. This creates a conditions where e1000_shutdown is called
after e1000_close, therefore hitting BUG_ON assert in free_msi_irqs.

Sometimes firmware may not properly initialize I347AT4_PAGE_SELECT causing
the probe of an igb i210 NIC to fail. This patch adds an addition zeroing
of this register during igb_get_phy_id to workaround this issue.

Thanks for Jochen Henneberg for the idea and original patch.

writel() in igb_configure_tx_ring() results in oops, because hw->hw_addr
is NULL. While other register access won't oops kernel because they use

Subject: igb: reset the PHY before reading the PHY ID

Several people have reported firmware leaving the I210/I211 PHY's page
select register set to something other than the default of zero. This
causes the first accesses, PHY_IDx register reads, to access something
else, resulting in device probe failure:

    igb: Intel(R) Gigabit Ethernet Network Driver - version 5.4.0-k
    igb: Copyright (c) 2007-2014 Intel Corporation.
    igb: probe of 0000:01:00.0 failed with error -2

This problem began for them after a previous patch I submitted was
applied:

    commit 2a3cdead8b408351fa1e3079b220fa331480ffbc
    Author: Aaron Sierra <asierra@xes-inc.com>
    Date:   Tue Nov 3 12:37:09 2015 -0600

        igb: Remove GS40G specific defines/functions

I personally experienced this problem after attempting to PXE boot from
I210 devices using this firmware:

    Intel(R) Boot Agent GE v1.5.78
    Copyright (C) 1997-2014, Intel Corporation

Resetting the PHY before reading from it, ensures the page select
register is in its default state and doesn't make assumptions about
the PHY's register set before the PHY has been probed.

Subject: igb: re-assign hw address pointer on reset after PCI error

Whenever the igb driver detects the result of a read operation returns
a value composed only by F's (like 0xFFFFFFFF), it will detach the
net_device, clear the hw_addr pointer and warn to the user that adapter's
link is lost - those steps happen on igb_rd32().

In case a PCI error happens on Power architecture, there's a recovery
mechanism called EEH, that will reset the PCI slot and call driver's
handlers to reset the adapter and network functionality as well.

We observed that once hw_addr is NULL after the error is detected on
igb_rd32(), it's never assigned back, so in the process of resetting
the network functionality we got a NULL pointer dereference in both
igb_configure_tx_ring() and igb_configure_rx_ring(). In order to avoid
such bug, this patch re-assigns the hw_addr value in the slot_reset
handler.

Subject: igb: close/suspend race in netif_device_detach

Similar to ixgbe, when an interface is part of a namespace it is
possible that igb_close() may be called while __igb_shutdown() is
running which ends up in a double free WARN and/or a BUG in
free_msi_irqs().

Extend the rtnl_lock() to protect the call to netif_device_detach() and
igb_clear_interrupt_scheme() in __igb_shutdown() and check for
netif_device_present() to avoid calling igb_clear_interrupt_scheme() a
second time in igb_close().

Also extend the rtnl lock in igb_resume() to netif_device_attach().

Subject: cxgb4: Synchronize access to mailbox

The issue comes when there are multiple threads attempting to use
the mailbox facility at the same time.
When DCB operations and interface up/down is run in a loop for every
0.1 sec, we observed mailbox collisions. And out of the two commands
one would fail with the present code, since we don't queue the second
command.

To overcome the above issue, added a queue to access the mailbox.
Whenever a mailbox command is issued add it to the queue. If its at
the head issue the mailbox command, else wait for the existing command
to complete. Usually command takes less than a milli-second to
complete.

Also timeout from the loop, if the command under execution takes
long time to run.

In reality, the number of mailbox access collisions is going to be
very rare since no one runs such abusive script.

Subject: net: ethernet: ti: cpdma: am437x: allow descs to be plased in ddr

It's observed that cpsw/cpdma is not working properly when CPPI
descriptors are placed in DDR instead of internal CPPI RAM on am437x
SoC:
- rx/tx silently stops processing packets;
- or - after boot it's working for sometime, but stuck once Network
load is increased (ping is working, but iperf is not).
(The same issue has not been reproduced on am335x and am57xx).

It seems that write to HDP register processed faster by interconnect
than writing of descriptor memory buffer in DDR, which is probably
caused by store buffer / write buffer differences as these functions
are implemented differently across devices. So, to fix this i come up
with two minimal, required changes:

1) all accesses to the channel register HDP/CP/RXFREE registers should
be done using sync IO accessors readl()/writel(), because all previous
memory writes writes have to be completed before starting channel
(write to HDP) or completing desc processing.

2) the change 1 only doesn't work on am437x and additional reading of
desc's field is required right after the new descriptor was filled
with data and before pointer on it will be stored in
prev_desc->hw_next field or HDP register.

In addition, to above changes this patch eliminates all relaxed ordering
I/O accessors in this driver as suggested by David Miller to avoid such
kind of issues in the future, but with one exception - relaxed IO accessors
will still be used to fill desc in cpdma_chan_submit(), which is safe as
there is read barrier at the end of write sequence, and because sync IO
accessors usage here will affect on net performance.

Subject: net: ethernet: ti: cpdma: fix desc re-queuing

The currently processing cpdma descriptor with EOQ flag set may
contain two values in Next Descriptor Pointer field:
- valid pointer: means CPDMA missed addition of new desc in queue;
- null: no more descriptors in queue.
In the later case, it's not required to write to HDP register, but now
CPDMA does it.

Hence, add additional check for Next Descriptor Pointer != null in
cpdma_chan_process() function before writing in HDP register.

Subject: net: ethernet: ti: cpsw: add support for descs pool size
 configuration

The CPSW CPDMA can process buffer descriptors placed as in internal
CPPI RAM as in DDR. This patch adds support in CPSW and CPDMA for
descs_pool_size mudule parameter, which defines total number of CPDMA CPPI
descriptors to be used for both ingress/egress packets processing:
 - memory size, required for CPDMA descriptor pool, is calculated basing
on number of descriptors specified by user in descs_pool_size and
CPDMA descriptor size and allocated from coherent memory (CMA area);
 - CPDMA descriptor pool will be allocated in DDR if pool memory size >
internal CPPI RAM or use internal CPPI RAM otherwise;
 - if descs_pool_size not specified in DT - the default value 256 will
be used which will allow to place CPDMA descriptors pool into the
internal CPPI RAM (current default behaviour);
 - CPDMA will ignore descs_pool_size if descs_pool_size = 0 for
backward comaptiobility with davinci_emac.

descs_pool_size is boot time setting and can't be changed once
CPSW/CPDMA is initialized.

Subject: net: ethernet: ti: cpsw: add support for ringparam configuration

The CPDMA uses one pool of descriptors for both RX and TX which by default
split between all channels proportionally depending on total number of
CPDMA channels and number of TX and RX channels. As result, more
descriptors will be consumed by TX path if there are more TX channels and
there is no way now to dedicate more descriptors for RX path.

So, add the ability to re-split CPDMA pool of descriptors between RX and TX
path via ethtool '-G' command wich will allow to configure and fix number
of descriptors used by RX and TX path, which, then, will be split between
RX/TX channels proportionally depending on RX/TX channels number and
weight. ethtool '-G' command will accept only number of RX entries and rest
of descriptors will be arranged for TX automatically.

Command:
  ethtool -G <devname> rx <number of descriptors>

defaults and limitations:
- minimum number of rx descriptors is 10% of total number of descriptors in
  CPDMA pool
- maximum number of rx descriptors is 90% of total number of descriptors in
  CPDMA pool
- by default, descriptors will be split equally between RX/TX path
- any values passed in "tx" parameter will be ignored

Usage:

 # ethtool -g eth0
	Pre-set maximums:
	RX:             7372
	RX Mini:        0
	RX Jumbo:       0
	TX:             0
	Current hardware settings:
	RX:             4096
	RX Mini:        0
	RX Jumbo:       0
	TX:             4096

 # ethtool -G eth0 rx 7372
 # ethtool -g eth0
	Ring parameters for eth0:
	Pre-set maximums:
	RX:             7372
	RX Mini:        0
	RX Jumbo:       0
	TX:             0
	Current hardware settings:
	RX:             7372
	RX Mini:        0
	RX Jumbo:       0
	TX:             820

Subject: net: netcp: extract eflag from desc for rx_hook handling

Extract the eflag bits from the received desc and pass it down
the rx_hook chain to be available for netcp modules. Also the
psdata and epib data has to be inspected by the netcp modules.
So the desc can be freed only after returning from the rx_hook.
So move knav_pool_desc_put() after the rx_hook processing.

Subject: net: netcp: store network statistics in 64 bits

Previously the network statistics were stored in 32 bit variable
which can cause some stats to roll over after several minutes of
high traffic. This implements 64 bit storage so larger numbers
can be stored.

Currently to parse phy-handle, driver doesn't check if the interface is
MAC to PHY. This patch add this check for all MAC to PHY interface types
supported by the driver.

Subject: net: netcp: use hw capability to remove FCS word from rx packets

Some of the newer Ethernet switch hw (such as that on k2e/l/g) can
strip the Etherenet FCS from packet at the port 0 egress of the switch.
So use this capability instead of doing it in software.

Subject: net: netcp: ale: update to support unknown vlan controls for NU
 switch

In NU Ethernet switch used on some of the Keystone SoCs, there is
separate UNKNOWNVLAN register for membership, unreg mcast flood, reg
mcast flood and force untag egress bits in ALE. So control for these
fields require different address offset, shift and size of field.
As this ALE has the same version number as ALE in CPSW found on other
SoCs, customization based on version number is not possible. So
use a configuration parameter, nu_switch_ale, to identify the ALE
ALE found in NU Switch. Different treatment is needed for NU Switch
ALE due to difference in the ale table bits, separate unknown vlan
registers etc. The register information available in ale_controls,
needs to be updated to support the netcp NU switch h/w. So it is not
constant array any more since it needs to be updated based
on ALE type. The header of the file is also updated to indicate it
supports N port switch ALE, not just 3 port. The version mask is
3 bits in NU Switch ALE vs 8 bits on other ALE types.

While at it, change the debug print to info print so that ALE
version gets displayed in boot log.

Subject: net: netcp: ale: use ale_status to size the ale table

ALE h/w on newer version of NetCP (K2E/L/G) does provide a ALE_STATUS
register for the size of the ALE Table implemented in h/w. Currently
for example we set ALE Table size to 1024 for NetCP ALE on
K2E even though the ALE Status/Documentation shows it has 8192 entries.
So take advantage of this register to read the size of ALE table supported
and use that value in the driver for the newer version of NetCP ALE.
For NetCP lite, ALE Table size is much less (64) and indicated by a size
of zero in ALE_STATUS. So use that as a default for now. While at it,
also fix the ale table size on 10G switch to 2048 per User guide

Subject: net: netcp: ale: add proper ale entry mask bits for netcp switch ALE

For NetCP NU Switch ALE, some of the mask bits are different than
defaults used in the driver. Add a new macro DEFINE_ALE_FIELD1 that use
a configurable mask bits and use it in the driver. These bits are set to
correct values by using the new variables added to cpsw_ale structure
and re-used in the macros. The parameter nu_switch_ale is configured by
the caller driver to indicate the ALE is for that switch and is used in
the ALE driver to do customization as needed.

Subject: mlx5: Fix naming convention with respect to UARs

This establishes a solid naming conventions for UARs. A UAR (User Access
Region) can have size identical to a system page or can be fixed 4KB
depending on a value queried by firmware. Each UAR always has 4 blue
flame register which are used to post doorbell to send queue. In
addition, a UAR has section used for posting doorbells to CQs or EQs. In
this patch we change names to reflect this conventions.

Subject: net/mlx5: Introduce blue flame register allocator

Here is an implementation of an allocator that allocates blue flame
registers. A blue flame register is used for generating send doorbells.
A blue flame register can be used to generate either a regular doorbell
or a blue flame doorbell where the data to be sent is written to the
device's I/O memory hence saving the need to read the data from memory.
For blue flame kind of doorbells to succeed, the blue flame register
need to be mapped as write combining. The user can specify what kind of
send doorbells she wishes to use. If she requested write combining
mapping but that failed, the allocator will fall back to non write
combining mapping and will indicate that to the user.
Subsequent patches in this series will make use of this allocator.

Subject: fm10k: request reset when mbx->state changes

Multiple IES API resets can cause a race condition where the mailbox
interrupt request bits can be cleared before being handled. This can
leave certain mailbox messages from the PF to be untreated and the PF
will enter in some inactive state. If this situation occurs, the IES API
will initiate a mailbox version reset which, then, trigger a mailbox
state change. Once this mailbox transition occurs (from OPEN to CONNECT
state), a request for reset will be returned.

This ensures that PF will undergo a reset whenever IES API encounters an
unknown global mailbox interrupt event or whenever the IES API
terminates.

The register bits related to this commit are now solely being handled by
the IES API. Recent changes in the IES API will allow an automatic

Additionally, remove the FM10K_FLAG_RX_TS_ENABLED, as it is not used now
that 1588 functionality has been removed.

Subject: liquidio: simplify octeon_flush_iq()

Because every call to octeon_flush_iq() has a hardcoded 1 for the
pending_thresh argument, simplify that function by removing that argument.
This avoids one atomic read as well.

Subject: net: make ndo_get_stats64 a void function

The network device operation for reading statistics is only called
in one place, and it ignores the return value. Having a structure
return value is potentially confusing because some future driver could
incorrectly assume that the return value was used.

Fix all drivers with ndo_get_stats64 to have a void function.

Subject: net: intel: e100: use new api ethtool_{get|set}_link_ksettings

The ethtool api {get|set}_settings is deprecated.
We move this driver to new api {get|set}_link_ksettings.

Subject: net/mlx5: Add interface to get reference to a UAR

A reference to a UAR is required to generate CQ or EQ doorbells. Since
CQ or EQ doorbells can all be generated using the same UAR area without
any effect on performance, we are just getting a reference to any
available UAR, If one is not available we allocate it but we don't waste
the blue flame registers it can provide and we will use them for
subsequent allocations.
We get a reference to such UAR and put in mlx5_priv so any kernel
consumer can make use of it.

Subject: IB/mlx5: Use blue flame register allocator in mlx5_ib

Make use of the blue flame registers allocator at mlx5_ib. Since blue
flame was not really supported we remove all the code that is related to
blue flame and we let all consumers to use the same blue flame register.
Once blue flame is supported we will add the code. As part of this patch
we also move the definition of struct mlx5_bf to mlx5_ib.h as it is only
used by mlx5_ib.

From 30aa60b3bd12bd79b5324b7b595bd3446ab24b52 Mon Sep 17 00:00:00 2001
From: Eli Cohen <eli@mellanox.com>
Date: Tue, 3 Jan 2017 23:55:27 +0200
Subject: IB/mlx5: Support 4k UAR for libmlx5

Add fields to structs to convey to kernel an indication whether the
library supports multi UARs per page and return to the library the size
of a UAR based on the queried value.

Subject: net: ethernet: ti: cpsw: extend limits for cpsw_get/set_ringparam

Allow to set number of descs close to possible values. In case of
minimum limit it's equal to number of channels to be able to set
at least one desc per channel. For maximum limit leave enough descs
number for tx channels.

Subject: mlxsw: spectrum: Make the add_matchall_tc_entry symmetric

Currently, the mlxsw spectrum driver only supports offloading the matchall
classifier together with the mirred action. To allow more matchall tc
offloads, make the code symmetric so that it can be easily extended later
on for other actions.

The code to handle rx checksumming was in the driver since its introduction
but for reasons unknown the feature flag was left out. Now it is possible
to enable this feature with ethtool.

Tested on my AR8161 ethernet card, there are no regressions observed in
netperf if this feature is enabled.

This patch adds a new parameter to the stmmac DT: snps,en-tx-lpi-clockgating.
It was ported from synopsys/dwc_eth_qos.c and it is useful if lpi tx clock
gating is needed by stmmac users also.

Subject: stmmac: move stmmac_clk, pclk, clk_ptp_ref and stmmac_rst to platform
 structure

This patch moves stmmac_clk, pclk, clk_ptp_ref and stmmac_rst to the
plat_stmmacenet_data structure. It also moves these platform variables
initialization to stmmac_platform. This was done for two reasons:

a) If PCI is used, platform related code is being executed in stmmac_main
resulting in warnings that have no sense and conceptually was not right

b) stmmac as a synopsys reference ethernet driver stack will be hosting
more and more drivers to its structure like synopsys/dwc_eth_qos.c.
These drivers have their own DT bindings that are not compatible with
stmmac's. One of the most important are the clock names, and so they need
to be parsed in the glue logic and initialized there, and that is the main
reason why the clocks were passed to the platform structure.

This patch adds a new glue driver called dwmac-dwc-qos-eth which
was based in the dwc_eth_qos as is. To assure retro-compatibility a slight
tweak was also added to stmmac_platform.

Subject: sh_eth: get rid of 'sh_eth_cpu_data::shift_rd0'

After checking all  the available manuals,  I have enough information to
conclude  that the 'shift_rd0' flag is only relevant  for the Ether cores
supporting so called "intelligent checksum" (and hence having CSMR) which
is indicated  by the 'hw_crc' flag.  Since  all the relevant SoCs now have
both these flags set, we can  at last  get  rid of the former flag...

Subject: sh_eth: add generic wake-on-lan support via magic packet
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Add generic functionality to support Wake-on-LAN using MagicPacket which
are supported by at least a few versions of sh_eth. Only add
functionality for WoL, no specific sh_eth versions are marked to support
WoL yet.

WoL is enabled in the suspend callback by setting MagicPacket detection
and disabling all interrupts expect MagicPacket. In the resume path the
driver needs to reset the hardware to rearm the WoL logic, this prevents
the driver from simply restoring the registers and to take advantage of
that sh_eth was not suspended to reduce resume time. To reset the
hardware the driver closes and reopens the device just like it would do
in a normal suspend/resume scenario without WoL enabled, but it both
closes and opens the device in the resume callback since the device
needs to be open for WoL to work.

One quirk needed for WoL is that the module clock needs to be prevented
from being switched off by Runtime PM. To keep the clock alive the
suspend callback need to call clk_enable() directly to increase the
usage count of the clock. Then when Runtime PM decreases the clock usage
count it won't reach 0 and be switched off.

Subject: net: qcom/emac: add ethtool support

Add support for some ethtool methods: get/set link settings, get/set
message level, get statistics, get link status, get ring params, get
pause params, and restart autonegotiation.

The code to collect the hardware statistics is moved into its own
function so that it can be used by "get statistics" method.

Subject: sfc: support ndo_get_phys_port_id even when !CONFIG_SFC_SRIOV

There's no good reason why this should be an SRIOV-only thing.
Thus, also move it out of SRIOV-specific files.

Subject: sfc: implement ndo_get_phys_port_name

Output is of the form p<port-number>.
Note that the port numbers don't necessarily map one-to-one to physical
 cages, partly because of 4x10G port modes on QSFP+ and partly because
 of hw/fw implementation details.

Subject: sfc: stop setting dev_port

Setting dev_port changes the device names allocated by systemd. Any devices
with a dev_port >0 will (in default distro configurations) have a suffix of
"d<port-number>" appended.

This is not something done by other drivers, and causes confusion for users.

Subject: net: netcp: correct netcp_get_stats function signature

Commit: bc1f44709cf2 - net: make ndo_get_stats64 a void function
and
Commit: 6a8162e99ef3 - net: netcp: store network statistics in 64 bits.

The commit 6a8162e99ef3 adds ndo_get_stats64 function as per old
signature which causes compilation error:

drivers/net/ethernet/ti/netcp_core.c:1951:28: error:
initialization from incompatible pointer type
  .ndo_get_stats64        = netcp_get_stats,

Hence correct netcp_get_stats function signature as per
the latest definition.

Some of the PCI MSI/MSI-X functions have been deprecated and it is
recommended to use the new pci_alloc_irq_vectors() function. Convert the
code over to use the new function. Also, modify the way in which the IRQs
are requested - try for multiple MSI-X/MSI first, then a single MSI/legacy
interrupt.

Subject: liquidio: use fallback for selecting txq

Remove assignment to ndo_select_queue so that fallback is used for
selecting txq.  Also remove the now-useless function that used to be
assigned to ndo_select_queue.

Subject: bnxt_en: Clear TPA flags when BNXT_FLAG_NO_AGG_RINGS is set.

Commit bdbd1eb59c56 ("bnxt_en: Handle no aggregation ring gracefully.")
introduced the BNXT_FLAG_NO_AGG_RINGS flag.  For consistency,
bnxt_set_tpa_flags() should also clear TPA flags when there are no
aggregation rings.

Subject: bnxt_en: Add the ulp_sriov_cfg hooks for bnxt_re RDMA driver.

Add the ulp_sriov_cfg callbacks when the number of VFs is changing.  This
allows the RDMA driver to provision RDMA resources for the VFs.

Subject: cxgb4: Remove redundant memset before memcpy

The region set by the call to memset, immediately overwritten by
the subsequent call to memcpy and thus makes the  memset redundant.

Also remove the memset((&info, 0, sizeof(info)) on line 398 because
info is memcpy()'ed to before being used in the loop and it isn't
used outside of the loop.

-/*  Synopsys DWC Ethernet Quality-of-Service v4.10a linux driver
- *
- *  This is a driver for the Synopsys DWC Ethernet QoS IP version 4.10a (GMAC).
- *  This version introduced a lot of changes which breaks backwards
- *  compatibility the non-QoS IP from Synopsys (used in the ST Micro drivers).
- *  Some fields differ between version 4.00a and 4.10a, mainly the interrupt

- *
- *  The GMAC is highly configurable at synthesis time. This driver has been
- *  developed for a subset of the total available feature set. Currently
- *  it supports:
- *  - TSO
- *  - Checksum offload for RX and TX.
- *  - Energy efficient ethernet.
- *  - GMII phy interface.
- *  - The statistics module.

Subject: cxgb4: Shutdown adapter if firmware times out or errors out

Perform an emergency shutdown of the adapter and stop it from
continuing any further communication on the ports or DMA to the
host. This is typically used when the adapter and/or firmware
have crashed and we want to prevent any further accidental
communication with the rest of the world. This will also force
the port Link Status to go down -- if register writes work --
which should help our peers figure out that we're down.

From de1deff994286f464d5cad152d97830a5155f9ba Mon Sep 17 00:00:00 2001
From: Edward Cree <ecree@solarflare.com>
Date: Fri, 13 Jan 2017 21:20:14 +0000
Subject: sfc: allow PIO more often

If an option descriptor has been sent on a queue but not followed by a
 packet, there will have been no completion event, so the read and write
 counts won't match and we'll think we can't do PIO.  This combines with
 the fact that we have two TX queues (for en/disable checksum offload),
 and that both must be empty for PIO to happen.
This patch adds a separate "packet_write_count" that tracks the most
 recent write_count we expect to see a completion event for; this excludes
 option descriptors but _includes_ PIO descriptors (even though they look
 like option descriptors).  This is then used, rather than write_count,
 in efx_nic_tx_is_empty().
We only bother to maintain packet_write_count on EF10, since on Siena
 (a) there are no option descriptors and it always equals write_count, and
 (b) there's no PIO, so we don't need it anyway.

Subject: sfc: get PIO buffer size from the NIC

The 8000 series SFC NICs have 4K PIO buffers, rather than the 2K of
 the 7000 series.  Rather than having a hard-coded PIO buffer size
 (ER_DZ_TX_PIOBUF_SIZE), read it from the GET_CAPABILITIES_V2 MCDI
 response.

Subject: net: mvneta: add xmit_more support

Basing on xmit_more flag of the skb, TX descriptors can be concatenated
before flushing. This commit delay Tx descriptor flush if the queue is
running and if there is more skb's to send.

A maximum allowed number of descriptors for flushing at once due to
MVNETA_TXQ_UPDATE_REG(q) reqisters limitation, is 255. Because of that
a new macro was added (MVNETA_TXQ_DEC_SENT_MASK) in order to ensure that
concatenated amount of descriptor does not exceed that value.

Subject: net: mvneta: add BQL support

Tests showed that when whole bandwidth is consumed, the latency for
various kind of traffic can reach high values. With saturated
link (e.g. with iperf from target to host) simple ping could take
significant amount of time. BQL proved to improve this situation
when implemented in mvneta driver. Measurements of ping latency
for 3 link speeds:
Speed | Latency w/o BQL | Latency with BQL
10    |      7-14 ms    |     3.5 ms
100   |      2-12 ms    |     0.6 ms
1000  |   often timeout |   up to 2ms

Decreasing latency as above result in sligt performance cost - 4kpps
(-1.4%) when pushing 64B packets via two bridged interfaces of Armada 38x.
For 1500B packets in the same setup, the mpstat tool showed +8% of
CPU occupation (default affinity, second CPU idle). Even though this
cost seems reasonable to take, considering other improvements.

This commit adds byte queue limit mechanism for the mvneta driver.

Subject: net: marvell: skge: use new api ethtool_{get|set}_link_ksettings

The ethtool api {get|set}_settings is deprecated.
We move this driver to new api {get|set}_link_ksettings.

The callback set_link_ksettings no longer update the value
of advertising, as the struct ethtool_link_ksettings is
defined as const.

As I don't have the hardware, I'd be very pleased if
someone may test this patch.

Ensures that we report the key and indirection table the NIC is using,
 rather than (if setting them failed earlier) what we wanted it to use.

Subject: net/mlx5e: Support bpf_xdp_adjust_head()

This patch adds bpf_xdp_adjust_head() support to mlx5e.

1. rx_headroom is added to struct mlx5e_rq.  It uses
   an existing 4 byte hole in the struct.
2. The adjusted data length is checked against
   MLX5E_XDP_MIN_INLINE and MLX5E_SW2HW_MTU(rq->netdev->mtu).
3. The macro MLX5E_SW2HW_MTU is moved from en_main.c to en.h.
   MLX5E_HW2SW_MTU is also moved to en.h for symmetric reason
   but it is not a must.

v2:
- Keep the xdp specific logic in mlx5e_xdp_handle()
- Update dma_len after the sanity checks in mlx5e_xmit_xdp_frame()

Subject: stmicro: add more information to Kconfig

This patch adds more info to stmicro' Kconfig files in order to be clearer
that the driver can be used by ethernet cards based on 10/100/1000/EQOS
Synopsys IP Cores.

EQOS was also added stmmac/Kconfig Kconfig, since dwmac4 is in fact EQoS,
one of Synopsys Ethernet IPs. More info at:
https://www.synopsys.com/dw/ipdir.php?ds=dwc_ether_qos

Subject: net:add one common config ARCH_WANT_RELAX_ORDER to support relax
 ordering

Relax ordering(RO) is one feature of 82599 NIC, to enable this feature can
enhance the performance for some cpu architecure, such as SPARC and so on.
Currently it only supports one special cpu architecture(SPARC) in 82599
driver to enable RO feature, this is not very common for other cpu architecture
which really needs RO feature.
This patch add one common config CONFIG_ARCH_WANT_RELAX_ORDER to set RO feature,
and should define CONFIG_ARCH_WANT_RELAX_ORDER in sparc Kconfig firstly.

Subject: net: Remove usage of net_device last_rx member

The network stack no longer uses the last_rx member of struct net_device
since the bonding driver switched to use its own private last_rx in
commit 9f242738376d ("bonding: use last_arp_rx in slave_last_rx()").

However, some drivers still (ab)use the field for their own purposes and
some driver just update it without actually using it.

Previously, there was an accompanying comment for the last_rx member
added in commit 4dc89133f49b ("net: add a comment on netdev->last_rx")
which asked drivers not to update is, unless really needed. However,
this commend was removed in commit f8ff080dacec ("bonding: remove
useless updating of slave->dev->last_rx"), so some drivers added later
on still did update last_rx.

Remove all usage of last_rx and switch three drivers (sky2, atp and
smc91c92_cs) which actually read and write it to use their own private
copy in netdev_priv.

Compile-tested with allyesconfig and allmodconfig on x86 and arm.

Subject: net/mlx5: Remove information print after attempt to load mlx5_ib
 module

Infiniband part of mlx5 driver can be compiled as a module
or as a part of bzImage (compiled in). In the second case,
the call to request_module will return an error -ENOENT.
It will cause to a misleading print "failed request module
on mlx5_ib".

This patch removes this print, In order to comply with mlx4.

Fixes: f66f049fb738 ("net/mlx5_core: Request the mlx5 IB module on driver load")

Subject: net/mlx5: Add MTPPS and MTPPSE registers infrastructure

Implement query and set functionality for MTPPS and MTPPSE registers.
MTPPS (Management Pulse Per Second) provides the device PPS capabilities,
configures the PPS in and out modules and holds the PPS in time stamp.
Query MTPPS is supported only when HCA_CAP.pps is set and modify is supported
when HCA_CAP.pps_modify is set.

MTPPSE (Management Pulse Per Second Event) configures the different event
generation modes for PPS. Supported when HCA_CAP.pps is set.

From ee7f12205abc21c2e83b266636e27b1cb2fd4e21 Mon Sep 17 00:00:00 2001
From: Eugenia Emantayev <eugenia@mellanox.com>
Date: Mon, 22 Aug 2016 14:57:41 +0300
Subject: net/mlx5e: Implement 1PPS support

This patch enables the 1PPS IN and 1PPS OUT support according
to the advertised HCA capability. Single pin may be configured
to one of the above mutual exclusive functions via standard
Linux tools and APIs. For example, testptp open source application.

Subject: net/mlx5e: Receive s-tagged packets in promiscuous mode

Today when the driver enter to promiscuous mode or vlan
filter is disabled, we add flow rule to receive any c-taggd
packets, therefore s-tagged packets are dropped.
In order to receive s-tagged packets as well we need to add
flow rule to receive any s-tagged packet.

Fixes: 7cb21b794baa ('net/mlx5e: Rename en_flow_table.c to en_fs.c')

Subject: net/mlx5: Implement PCAM, MCAM access register commands

Introduced registers will expose capabilities of new registers and
features related to port/management.
Driver will query MCAM and PCAM in order to avoid failing on old
firmwares with lack of support.

- rx_symbol_errors_phy: Number of symbol errors that were not corrected
  by FEC correction algorithm or that FEC was not active on this interface.

- rx_corrected_bits_phy: Number of corrected bits according to active
  FEC (RS/FC).

Subject: Revert "net: qcom/emac: configure the external phy to allow pause
 frames"

This reverts commit 3e884493448131179a5b7cae1ddca1028ffaecc8.

With commit 529ed1275263 ("net: phy: phy drivers should not set
SUPPORTED_[Asym_]Pause"), phylib now handles automatically enabling
pause frame support in the PHY, and the MAC driver should follow suit.

Since the EMAC driver driver does this,  we no longer need to force

Subject: mlx4: support __GFP_MEMALLOC for rx

Commit 04aeb56a1732 ("net/mlx4_en: allocate non 0-order pages for RX
ring with __GFP_NOMEMALLOC") added code that appears to be not needed at
that time, since mlx4 never used __GFP_MEMALLOC allocations anyway.

As using memory reserves is a must in some situations (swap over NFS or
iSCSI), this patch adds this flag.

Note that this driver does not reuse pages (yet) so we do not have to
add anything else.

Subject: cxgb4: hide unused warnings

The two new variables are only used inside of an #ifdef and cause
harmless warnings when that is disabled:

drivers/net/ethernet/chelsio/cxgb4/cxgb4_main.c: In function 'init_one':
drivers/net/ethernet/chelsio/cxgb4/cxgb4_main.c:4646:9: error: unused variable 'port_vec' [-Werror=unused-variable]
drivers/net/ethernet/chelsio/cxgb4/cxgb4_main.c:4646:6: error: unused variable 'v' [-Werror=unused-variable]

This adds another #ifdef around the declarations.

Subject: net: ethernet: ti: cpsw: remove dual check from common res usage
 function

Common res usage is possible only in case an interface is
running. In case of not dual emac here can be only one interface,
so while ndo_open and switch mode, only one interface can be opened,
thus if open is called no any interface is running ... and no common
res are used. So remove check on dual emac, it will simplify
code/understanding and will match the name it's called.

Subject: net: ethernet: ti: cpsw: don't disable interrupts in ndo_open

No need to disable interrupts if no open devices,
they are disabled anyway.

Even no need to disable interrupts if some ndev is opened, In this
case shared resources are not touched, only parameters of ndev shell,
so no reason to disable them also. Removed lines have proved it.

So, no need in redundant check and interrupt disable.

In preparation for adding SYSTEMPORT Lite, which has twice as less transmit
queues than SYSTEMPORT make sure we do allocate TX rings based on the
systemport,txq property to get an appropriate memory footprint.

Subject: net: systemport: Add support for SYSTEMPORT Lite

Add supporf for the SYSTEMPORT Lite Ethernet controller, this piece of hardware
is largely based on the full-blown SYSTEMPORT and differs in the following:

- no full-blown UniMAC, instead we have the MagicPacket matching from UniMAC at
  same offset, and a GMII Interface Block (GIB) for the MAC-level stuff, since
  we are always interfaced to an Ethernet switch which is fully Ethernet compliant
  shortcuts could be made

- 16 transmit queues, whose interrupts are moved into the first Level-2 interrupt
  controller bank

- slight TDMA offset change (a register was inserted after TDMA_STATUS, *sigh*)

- 256 RX descriptors (512 words) and 256 TX descriptors (not visible)

As a consequence of these two things, update the code paths accordingly to
differentiate the full-blown from the light version.

Subject: bnx2x: avoid two atomic ops per page on x86

Commit 4cace675d687 ("bnx2x: Alloc 4k fragment for each rx ring buffer
element") added extra put_page() and get_page() calls on arches where
PAGE_SIZE=4K like x86

Reorder things to avoid this overhead.

Subject: net: qcom/emac: rename emac_phy to emac_sgmii and move it

The EMAC has an internal PHY that is often called the "SGMII".  This
SGMII is also connected to an external PHY, which is managed by phylib.
These dual PHYs often cause confusion.  In this case, the data structure
for managing the SGMII was mis-named and located in the wrong header file.

Structure emac_phy is renamed to emac_sgmii to clearly indicate it applies
to the internal PHY only.  It also also moved from emac_phy.h (which
supports the external PHY) to emac_sgmii.h (where it belongs).

To keep the changes minimal, only the structure name is changed, not
the names of any variables of that type.

Subject: net: qcom/emac: claim the irq only when the device is opened

During reset, functions emac_mac_down() and emac_mac_up() are called,
so we don't want to free and claim the IRQ unnecessarily.  Move those
operations to open/close.

Subject: net: stmmac: dwmac-meson8b: make the RGMII TX delay configurable

Prior to this patch we were using a hardcoded RGMII TX clock delay of
2ns (= 1/4 cycle of the 125MHz RGMII TX clock). This value works for
many boards, but unfortunately not for all (due to the way the actual
circuit is designed, sometimes because the TX delay is enabled in the
PHY, etc.). Making the TX delay on the MAC side configurable allows us
to support all possible hardware combinations.

This allows fixing a compatibility issue on some boards, where the
RTL8211F PHY is configured to generate the TX delay. We can now turn
off the TX delay in the MAC, because otherwise we would be applying the
delay twice (which results in non-working TX traffic).

Subject: mlxsw: reg: add the Monitoring Packet Sampling Configuration Register

The MPSC register allows to configure ingress packet sampling on specific
port of the mlxsw device. The sampled packets are then trapped via
PKT_SAMPLE trap.

Subject: mlxsw: spectrum: Add packet sample offloading support

Using the MPSC register, add the functions that configure port-based
packet sampling in hardware and the necessary datatypes in the
mlxsw_sp_port struct. In addition, add the necessary trap for sampled
packets and integrate with matchall offloading to allow offloading of the
sample tc action.

The current offload support is for the tc command:

tc filter add dev <DEV> parent ffff: \
	  matchall skip_sw \
	  action sample rate <RATE> group <GROUP> [trunc <SIZE>]

Where only ingress qdiscs are supported, and only a combination of
matchall classifier and sample action will lead to activating hardware
packet sampling.

Subject: net: broadcom: bnx2x: use new api ethtool_{get|set}_link_ksettings

The ethtool api {get|set}_settings is deprecated.
We move this driver to new api {get|set}_link_ksettings.

As I don't have the hardware, I'd be very pleased if
someone may test this patch.

Subject: net/mlx5: Use exact encap header size for the FW input buffer

The current code is allocating the max encap size supported by
the firmware and not the size requested by the caller, fix that.

Also, spare a warning when the size of the encapsulation headers
is bigger from what is supported by the firmware.

Subject: net/mlx5e: Add TC offloads matching on IPv6 encapsulation headers

Enhance the parsing of offloaded TC rules to set HW matching on outer
IPv6 encapsulation headers. This effectively adds support for TC tunnel
key release action (decapsulation) of SRIOV offloads over IPv6 tunnels.

Subject: net/mlx5e: Use the full tunnel key info for encapsulation offload
 house-keeping

Currently we use subset of the input tunnel key fields (id, ip daddr,
dst port) which are provided by upper layers to indentify flows that should
go through the same encapsulation and maintain the HW encapsulation table.

This is redundant and can get us wrong.

Instead, keep a copy of the ip tunnel info provided by the user
through TC and have the tunnel key part as the key to our internal hash.

  min(max eswitch table size, max flow counters * num flow groups)

where the max values are read from the firmware and the number of
flow groups is hard-coded as before this change.

We don't know upfront the division of flows to group. This setup allows
each group to be of size up to the where we want to support (we mandate
pairing of flows with counters for offloading). Thus, we don't expect
multiple occurences for a group which in turn adds steering hops.

Subject: net/mlx5: Add support for setting VF min rate

Add support for SRIOV VF min rate guarantee by using the TSAR BW share
weights mechanism.

The TSAR BW share vport attribute represents the weight of that vport
among the other vports weights which means that the actual vport BW
percentage is the same vport weight percentage among the total vports
weights sum.

Subject: bpf: add initial bpf tracepoints

This work adds a number of tracepoints to paths that are either
considered slow-path or exception-like states, where monitoring or
inspecting them would be desirable.

For bpf(2) syscall, tracepoints have been placed for main commands
when they succeed. In XDP case, tracepoint is for exceptions, that
is, f.e. on abnormal BPF program exit such as unknown or XDP_ABORTED
return code, or when error occurs during XDP_TX action and the packet
could not be forwarded.

Both have been split into separate event headers, and can be further
extended. Worst case, if they unexpectedly should get into our way in
future, they can also removed [1]. Of course, these tracepoints (like
any other) can be analyzed by eBPF itself, etc. Example output:

  # ./perf record -a -e bpf:* sleep 10
  # ./perf script

Subject: net: thunderx: Support to configure queue sizes from ethtool

Adds support to set Rx/Tx queue sizes from ethtool. Fixes
an issue with retrieving queue size. Also sets SQ's CQ_LIMIT
based on configured Tx queue size such that HW doesn't process
SQEs when there is no sufficient space in CQ.

Subject: net: thunderx: Leave serdes lane config on 81/83xx to firmware

For DLMs and SLMs on 80/81/83xx, many lane configurations
across different boards are coming up. Also kernel doesn't have
any way to identify board type/info and since firmware does,
just get rid of figuring out lane to serdes config and take
whatever has been programmed by low level firmware.

Subject: sfc: reduce severity of PIO buffer alloc failures

PIO buffer allocation can fail for two valid reasons:
 - we've run out of them (results in -ENOSPC)
 - the NIC configuration doesn't support them (results in -EPERM)
Since both these failures are expected netif_err is excessive.

Subject: sfc: fixes to filter restore handling

If the NIC is switched from full-featured to low-latency, encapsulated
 filters are no longer available, and this causes errors. This patch
 removes those filters from the filter table on restore.
Also, if filters which are removed by the above, or which we fail to
 insert when restoring filters, were UC, MC or broadcast default
 filters, invalidate the corresponding vlan->default_filters entry.

Subject: sfc: insert catch-all filters for encapsulated traffic

8000 series adapters support filtering VXLAN, NVGRE and GENEVE traffic
 based on inner fields, and when the NIC recognises such traffic, it
 does not match unencapsulated traffic filters any more.  So add catch-
 all filters for encapsulated traffic on supporting platforms.
Although recognition of VXLAN and GENEVE is based on UDP ports, and thus
 will not occur until the driver (on the primary PF) notifies the
 firmware of UDP ports to use, NVGRE will always be recognised, hence
 without this patch 8000 series adapters will drop all NVGRE traffic.

Partly based on patches by Jon Cooper <jcooper@solarflare.com>.

Subject: ravb: Add tx and rx clock internal delays mode of APSR

This patch enables tx and rx clock internal delay modes (TDM and RDM).

This is to address a failure in the case of 1Gbps communication using the
by salvator-x board with the KSZ9031RNX phy. This has been reported to
occur with both the r8a7795 (H3) and r8a7796 (M3-W) SoCs.

With this change APSR internal delay modes are enabled for
"rgmii-id", "rgmii-rxid" and "rgmii-txid" phy modes as follows:

phy mode   | ASPR delay mode
-----------+----------------
rgmii-id   | TDM and RDM
rgmii-rxid | RDM
rgmii-txid | TDM

Subject: net: qcom/emac: display the phy driver info after we connect

The PHY driver is attached only when the driver calls
phy_connect_direct().  Calling phy_attached_print() to display
information about the PHY driver prior to that point is meaningless.
The interface can be brought down, a new PHY driver can be loaded,
and the interface then brought back up.  This is the correct time
to display information about the attached driver.

Since phy_attached_print() also prints information about the
interrupt, that needs to be set as well.

Regardless of how the external PHY is configured, the internal PHY
(the "SGMII" block) is capable of configuring the SGMII link automatically.
When the external PHY link comes up, regardless of how it is configured,
the SGMII link is configured automatically.

Subject: net: qcom/emac: add an error interrupt handler for the sgmii

The SGMII (internal PHY) can report decode errors via an interrupt.  It
can also report autonegotiation status changes, but we don't need to track
those.  The SGMII can recover automatically from most decode errors, so
we only reset the interface if we get multiple consecutive errors.

It's possible for bogus decode errors to be reported while the link is
being brought up.  The interrupt is registered when the interface is
opened, and it's enabled after the link is up.

From 6ad20165d376fa07919a70e4f43dfae564601829 Mon Sep 17 00:00:00 2001
From: Eric Dumazet <edumazet@google.com>
Date: Mon, 30 Jan 2017 08:22:01 -0800
Subject: drivers: net: generalize napi_complete_done()

napi_complete_done() allows to opt-in for gro_flush_timeout,
added back in linux-3.19, commit 3b47d30396ba
("net: gro: add a per device gro flush timer")

This allows for more efficient GRO aggregation without
sacrifying latencies.

Subject: net/mlx4_core: Device revision support

The device revision field returned by the NodeInfo MAD is incorrect
on ConnectX3 devices.

This patch is driver side handling to complete a FW fix added at 2.11.1172.
INIT_HCA - bit at offset 0x0C.12 is set to 1 so that FW will report
correct device revision.

Older FW versions won't be affected from turning on that bit,
no capability bit is needed.

Subject: net/mlx4_en: Adding support of turning off link autonegotiation via
 ethtool

This feature will allow the user to disable auto negotiation
on the port for mlx4 devices while setting the speed is limited
to 1GbE speeds.
Other speeds will not be accepted in autoneg off mode.

This functionality is permitted providing that the firmware
is compatible with this feature.
The above is determined by querying a new dedicated capability
bit in the device.

Subject: sh_eth: rename EESIPR bits

Since the  commit  b0ca2a21f769 ("sh_eth: Add support of SH7763 to sh_eth")
the *enum* declaring the EESIPR bits (interrupt mask) went out of sync with
the *enum* declaring the EESR bits (interrupt status) WRT  bit naming  and
formatting. I'd like to restore the consistency by using EESIPR as the bit
name prefix, renaming the *enum* to EESIPR_BIT, and (finally) renaming the
bits according to the available  Renesas SH77{34|63} manuals; additionally,
reconstruct  couple names using  the EESR bit declaration above...

Renesas SH77{34|63} manuals  describe more EESIPR bits than the current
driver. Declare the new bits with the end goal of using the bit names
instead of the bare numbers  for  the 'sh_eth_cpu_data::eesipr_value'
initializers...

Subject: sh_eth: stop using bare numbers for EESIPR values

Now  that we  have almost all EESIPR bits declared (and those  that are
still not are most probably reserved anyway) we can at last replace the
bare  numbers used for 'sh_eth_cpu_data::eesipr_value' initializers with
the bit names ORed together...

Subject: sfc: fix an off-by-one compare on an array size

encap_type should be checked to see if it is greater or equal to
the size of array map to fix an off-by-one array size check. This
fixes an array overrun read as detected by static analysis by
CoverityScan, CID#1398883 ("Out-of-bounds-read")

Fixes: 9b41080125176841e ("sfc: insert catch-all filters for encapsulated traffic")

Subject: net: aquantia: atlantic: use new api ethtool_{get|set}_link_ksettings

The ethtool api {get|set}_settings is deprecated.
We move this driver to new api {get|set}_link_ksettings.

As I don't have the hardware, I'd be very pleased if
someone may test this patch.

Subject: net: bgmac: allocate struct bgmac just once & don't copy it
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

So far were were allocating struct bgmac in 3 places: platform code,
bcma code and shared bgmac_enet_probe function. The reason for this was
bgmac_enet_probe:
1) Requiring early-filled struct bgmac
2) Calling alloc_etherdev on its own in order to use netdev_priv later

This solution got few drawbacks:
1) Was duplicating allocating code
2) Required copying early-filled struct
3) Resulted in platform/bcma code having access only to unused struct

Solve this situation by simply extracting some probe code into the new
bgmac_alloc function.

Subject: net: bgmac: drop struct bcma_mdio we don't need anymore
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Adding struct bcma_mdio was a workaround for bcma code not having access
to the struct bgmac used in the core code. Now we don't duplicate this
struct we can just use it internally in bcma code.

This simplifies code & allows access to all bgmac driver details from
all places in bcma code.

Subject: net: bgmac: use PHY subsystem for initializing PHY
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This adds support for using bgmac with PHYs supported by standalone PHY
drivers. Having any PHY initialization in bgmac is hacky and shouldn't
be extended but rather removed if anyone has hardware to test it.

Subject: net: ethernet: ti: cpsw: fix NULL pointer dereference in switch mode

In switch mode on struct cpsw_slave->ndev field will be initialized with
proper value only for the one cpsw slave port, as result
cpsw_get_usage_count() will generate "Unable to handle kernel NULL pointer
dereference" exception when first ethernet interface is opening
cpsw_ndo_open(). This issue causes boot regression on AM335x EVM and
reproducible on am57xx-evm (switch mode).
Fix it by adding additional check for !cpsw->slaves[i].ndev in
cpsw_get_usage_count().

Subject: xgene_enet: remove bogus forward declarations

The device match tables for both the xgene_enet driver and its phy driver
have forward declarations that declare an array without a length, leading
to a clang warning when they are not followed by an actual defitinition:

drivers/net/ethernet/apm/xgene/../../../phy/mdio-xgene.h:135:34: warning: tentative array definition assumed to have one element
drivers/net/ethernet/apm/xgene/xgene_enet_main.c:33:36: warning: tentative array definition assumed to have one element

The declarations for the mdio driver are even in a header file, so they
cause duplicate definitions of the tables for each file that includes
them.

This removes all four forward declarations and moves the actual
definitions up a little, so they are in front of their first user. For
the OF match tables, this means having to remove the #ifdef around them,
and passing the actual structure into of_match_device(). This has no
effect on the generated object code though, as the of_match_device
function has an empty stub that does not evaluate its argument, and
the symbol gets dropped either way.

Subject: i40e: don't allow i40e_vsi_(add|kill)_vlan to operate when VID<1

Now that we have the separate i40e_(add|rm)_vlan_all_mac functions, we
should not be using the i40e_vsi_kill_vlan or i40e_vsi_add_vlan
functions when PVID is set or when VID is less than 1. This allows us to
remove some checks in i40e_vsi_add_vlan and ensures that callers which
need to handle VID=0 or VID=-1 don't accidentally invoke the VLAN mode
handling used to convert filters when entering VLAN mode. We also update
the functions to take u16 instead of s16 as well since they no longer
expect to be called with VID=I40E_VLAN_ANY.

Fold the check for determining when to call i40e_put_mac_in_vlan directly

ahead of time. This allows us to just call i40e_put_mac_in_vlan directly

Subject: i40e: no need to check is_vsi_in_vlan before calling
 i40e_del_mac_all_vlan

This function won't be appreciably slower when in VLAN mode, so there is
no real reason to not just call it directly. In either case, we still
must search the full table for a MAC/VLAN pair. We do get to stop
searching a tiny bit early in the case of knowing we are not in VLAN
mode, but this is a minor savings and we can avoid the code complexity
by not having to worry about the check.

Subject: i40e: rename i40e_put_mac_in_vlan and i40e_del_mac_all_vlan

These functions purpose is to add a new MAC filter correctly, whether
we're using VLANs or not. Their goal is to ensure that all active VLANs
get the new MAC filter. Rename them so that their intent is clear. They
function correctly regardless of whether we have any active VLANs or
only have I40E_VLAN_ANY filters. The new names convey how they function
in a more clear manner.

Subject: i40e: avoid O(n^2) loop when deleting all filters

Use __i40e_del_filter instead of using i40e_del_filter() which will
avoid doing an additional search to delete a filter we already have the
pointer for.

Subject: i40e: when adding or removing MAC filters, correctly handle VLANs

Instead of using i40e_add_filter or i40e_del_filter directly, when
adding a MAC address, we should normally be using i40e_add_mac_filter or
i40e_del_mac_filter. These functions correctly handle the various cases
of VLAN mode or PVID settings. This ensures consistency and avoids the
issues that can occur with the recent addition of a WARN_ON() in
i40e_sync_vsi_filters.

Subject: i40e: Deprecating unused macro

I40E_MAC_X710 was supposed to be for 10G and I40E_MAC_XL710
was supposed to be for 40G. But function i40e_is_mac_710
sets I40E_MAC_XL710 for all device IDS, I40E_MAC_X710 is not
used at all. As there is nothing to compare there is no need
for this function. Thus deprecating this extra macro and
removing this function entirely and replacing it with a direct
check.

Subject: i40evf: remove unused device ID

This device ID was intended for use when running Linux VF drivers under
Hyper-V, but we have determined that it is not necessary. Since it is
unused, and will never be used, remove it.

Subject: i40e: remove unnecessary __packed

'struct i40e_dma_mem' defined with 'packed' directive causing kernel
unaligned errors on sparc.

e.g.
i40e: Intel(R) Ethernet Connection XL710 Network Driver - version
1.6.16-k
i40e: Copyright (c) 2013 - 2014 Intel Corporation.
Kernel unaligned access at TPC[44894c] dma_4v_alloc_coherent+0x1ac/0x300
Kernel unaligned access at TPC[44894c] dma_4v_alloc_coherent+0x1ac/0x300
Kernel unaligned access at TPC[44894c] dma_4v_alloc_coherent+0x1ac/0x300
Kernel unaligned access at TPC[44894c] dma_4v_alloc_coherent+0x1ac/0x300
Kernel unaligned access at TPC[44894c] dma_4v_alloc_coherent+0x1ac/0x300
i40e 0000:03:00.0: fw 5.1.40981 api 1.5 nvm 5.04 0x80002548 0.0.0

This can be fixed with get_unaligned/put_unaligned(). However no
reference in driver shows that 'struct i40e_dma_mem' directly shoved
into NIC hardware. But instead fields of the struct are being read and
used for hardware. Therefore, __packed is unnecessary for 'struct
i40e_dma_mem'.

In addition, although 'struct i40e_virt_mem' doesn't cause any
unaligned access, keeping it packed is unnecessary as well because
of aforementioned reason.

This change make 'struct i40e_dma_mem' and 'struct i40e_virt_mem'
unpacked.

Subject: i40e: Quick refactor to start moving data off stack and into Tx
 buffer info

This patch does some quick work to pull some of the data off of the stack
and hopefully start storing it in the Tx buffer info section of the Tx
ring.  Ideally we should be moving away from having to store much of
anything on the stack and can just maintain it all in the descriptor rings.

Subject: i40e: refactor macro INTRL_USEC_TO_REG

This patch refactors the macro INTRL_USEC_TO_REG into a static inline
function and fixes a couple subtle bugs caused by the macro.

This patch fixes a bug which was caused by passing a bad register value
to the firmware.  If enabling interrupt rate limiting, a non-zero value
for the rate limit must be used.  Otherwise the firmware sets the
interrupt rate limit to the maximum value.  Due to the limited
resolution of the register, attempting to set a value of 1, 2, or 3
would be rounded down to 0 and limiting was left enabled, causing
unexpected behavior.

This patch also fixes a possible bug in which using the macro itself can
introduce unintended side-affects because the macro argument is used
more than once in the macro definition (e.g. a variable post-increment
argument would perform a double increment on the variable).

Without this patch, attempting to set interrupt rate limits of 1, 2, or
3 results in unexpected behavior and future use of this macro could
cause subtle bugs.

Subject: i40e: add interrupt rate limit verbosity

Due to the resolution of the register controlling interrupt rate
limiting, setting certain values for the interrupt rate limit make it
appear as though the limiting is not completely accurate.  The problem
is that the interrupt rate limit is getting rounded down to the nearest
multiple of 4.  This patch fixes the problem by adding some feedback to
the user as to the actual interrupt rate limit being used when it
differs from the requested limit.  Without this patch setting interrupt
rate limits may appear to behave inaccurately.

Subject: sfc: get rid of custom busy polling code

In linux-4.5, busy polling was implemented in core
NAPI stack, meaning that all custom implementation can
be removed from drivers.

Not only we remove lot's of tricky code, we also remove
one lock operation in fast path.

Subject: sfc-falcon: get rid of custom busy polling code

In linux-4.5, busy polling was implemented in core
NAPI stack, meaning that all custom implementation can
be removed from drivers.

Not only we remove lot's of tricky code, we also remove
one lock operation in fast path.

Subject: cxgb4: Fix uld_send() for ctrl pkts

Without any uld being loaded, uld_txq_info[] will be NULL. uld_send()
is also used for sending control work requests(for eg: setting filter)
that dont require any ulds to be loaded. Hence move uld_txq_info[]
assignment after ctrl_xmit().

Also added a NULL check for uld_txq_info[].

Fixes: 94cdb8bb993a (cxgb4: Add support for dynamic allocation
       of resources for ULD).

Subject: hns_enet: use cpumask_var_t for on-stack mask

On large SMP builds, we can run into a build warning:

drivers/net/ethernet/hisilicon/hns/hns_enet.c: In function 'hns_set_irq_affinity.isra.27':
drivers/net/ethernet/hisilicon/hns/hns_enet.c:1242:1: warning: the frame size of 1032 bytes is larger than 1024 bytes [-Wframe-larger-than=]

The solution here is to use cpumask_var_t, which can use dynamic
allocation when CONFIG_CPUMASK_OFFSTACK is enabled.

Subject: be2net: get rid of custom busy poll code

Compared to custom busy_poll, the generic NAPI one is better, since
it allows to use GRO, and it removes a lot of code and extra locked
operations in fast path.

Subject: myri10ge: get rid of custom busy poll code

Compared to custom busy_poll, the generic NAPI one is simpler and
removes a lot of code. It removes one atomic in the fast path (when
busy poll is not in action) since we do not have to use an extra
spinlock.

From 5226b7919641f285bf0f8db84deeb3920b160ec7 Mon Sep 17 00:00:00 2001

Subject: cxgb4: get rid of custom busy poll code

In linux-4.5, busy polling was implemented in core
NAPI stack, meaning that all custom implementation can
be removed from drivers.

Not only we remove lot of code, we also remove one spin_lock()
from driver fast path.

Subject: mlxsw: core: Introduce flexible keys support

Hardware supports matching on so called "flexible keys". The idea is to
assemble an optimal key to use for matching according to the fields in
packet (elements) requested by user. Certain sets of elements are
combined into pre-defined blocks. There is a picker to find needed blocks.
Keys consist of 1..n blocks.

Alongside with that, an initial portion of elements is introduced in order
to be able to offload basic cls_flower rules.

Picked keys are cached so multiple rules could share them.

There is an encode function provided that takes care of encoding key and
mask values according to given key.

Subject: mlxsw: core: Introduce flexible actions support

Each entry which is matched during ACL lookup points to an action set.
This action set contains up to three separate actions. If more actions
are needed to be chained, the extended set is created to hold them
in KVD linear area.

This patch implements handling of sets and encoding of actions.
Currectly, only two actions are supported. Drop and forward. Forward
action uses PBS pointer to KVD linear area, so the action code needs to
take care of this as well.

Subject: mlxsw: spectrum: Introduce ACL core with simple TCAM implementation

Add ACL core infrastructure for Spectrum ASIC. This infra provides an
abstraction layer over specific HW implementations. There are two basic
objects used. One is "rule" and the second is "ruleset" which serves as a
container of multiple rules. In general, within one ruleset the rules are
allowed to have multiple priorities and masks. Each ruleset is bound to
either ingress or egress a of port netdevice.

The initial TCAM implementation is very simple and limited. It utilizes
parman lsort manager to take care of TCAM region layout.

Subject: mlxsw: spectrum: Implement TC flower offload

Extend the existing setup_tc ndo call and allow to offload cls_flower
rules. Only limited set of dissector keys and actions are supported now.
Use previously introduced ACL infrastructure to offload cls_flower rules
to be processed in the HW.

From 617f01211bafed65b5cb2fa5b671e839c7f2af86 Mon Sep 17 00:00:00 2001
From: Eric Dumazet <edumazet@google.com>
Date: Sat, 4 Feb 2017 15:24:51 -0800
Subject: 8139too: use napi_complete_done()

Use napi_complete_done() instead of __napi_complete() to :

1) Get support of gro_flush_timeout if opt-in
2) Not rearm interrupts for busy-polling users.
3) use standard NAPI API.

Subject: 8139cp: use napi_complete_done()

Use napi_complete_done() instead of __napi_complete() to :

1) Get support of gro_flush_timeout if opt-in
2) Not rearm interrupts for busy-polling users.
3) use standard NAPI API.
4) Eventually get rid of napi_gro_flush() in the future.

Subject: ks8695net: add GRO support

Use napi_complete_done() instead of __napi_complete() to :

1) Get support of gro_flush_timeout if opt-in
2) Not rearm interrupts for busy-polling users.
3) use standard NAPI API.

Note that rx_lock seems to be useless, NAPI logic should
not need this extra care.

Date: Thu, 19 Nov 2015 17:12:26 +0200
Subject: net/mlx5: Configure cache line size for start and end padding

There is a hardware feature that will pad the start or end of a DMA to
be cache line aligned to avoid RMWs on the last cache line. The default
cache line size setting for this feature is 64B. This change configures
the hardware to use 128B alignment on systems with 128B cache lines.

In addition we lower bound MPWRQ stride by HCA cacheline in mlx5e,
MPWRQ stride should be at least the HCA cacheline, the current default
is 64B and in case HCA_CAP.cach_line_128byte capability is set, MPWRQ RX
stride will automatically be aligned to 128B.

Subject: net/mlx5: TX WQE update

Add new TX WQE fields for Connect-X5 vlan insertion support,
type and vlan_tci, when type = MLX5_ETH_WQE_INSERT_VLAN the
HW will insert the vlan and prio fields (vlan_tci) to the packet.

Those bits and the inline header fields are mutually exclusive, and
valid only when:
MLX5_CAP_ETH(mdev, wqe_inline_mode) == MLX5_CAP_INLINE_MODE_NOT_REQUIRED
and MLX5_CAP_ETH(mdev, wqe_vlan_insert),
who will be set in ConnectX-5 and later HW generations.

Subject: net/mlx5e: Tx, no inline copy on ConnectX-5

ConnectX-5 and later HW generations will report min inline mode ==
MLX5_INLINE_MODE_NONE, which means driver is not required to copy packet
headers to inline fields of TX WQE.

When inline is not required, vlan insertion will be handled in the
TX descriptor rather than copy to inline.

For LSO case driver is still required to copy headers, for the HW to
duplicate on wire.

This will improve CPU utilization and boost TX performance.

Tested with pktgen burst single flow:
CPU: Intel(R) Xeon(R) CPU E5-2680 v3 @ 2.50GHz
HCA: Mellanox Technologies MT28800 Family [ConnectX-5 Ex]

Before: 15.1Mpps
After:  17.2Mpps
Improvement: 14%

Subject: net/mlx5e: Bring back bfreg uar map dedicated pointer

4K Uar series modified the mlx5e driver to use the new bfreg API,
and mistakenly removed the sq->uar_map iomem data path dedicated
pointer, which was meant to be read from xmit path for cache locality
utilization.

Fix that by returning that pointer to the SQ struct.

We always use zero delay before queueing a work on the ordered workqueue

Subject: mlxsw: spectrum_router: Use ordered workqueue for neigh updates

We currently associate each neighbour entry with a work item, so it's
not possible to have multiple events queued for the same neighbour
entry. However, this is about to be changed so that the neighbour entry
is only resolved when the work item is scheduled.

The above can result in a mismatch between the kernel's and the device's
neighbour table, unless the associated work items are processed in the
order in which they were submitted.

Do that by migrating the NEIGH_UPDATE work items to be processed in the
ordered workqueue which was recently introduced in mlxsw in commit
a3832b31898f ("mlxsw: core: Create an ordered workqueue for FIB
offload").

Subject: mlxsw: spectrum_router: Simplify neighbour reflection

Up until now we had two interfaces for neighbour related configuration:
ndo_neigh_{construct,destroy} and NEIGH_UPDATE netevents. The ndos were
used to add and remove neighbours from the driver's cache, whereas the
netevent was used to reflect the neighbours into the device's tables.

However, if the NUD state of a neighbour isn't NUD_VALID or if the
neighbour is dead, then there's really no reason for us to keep it
inside our cache. The only exception to this rule are neighbours that
are also used for nexthops, which we periodically refresh to get them
resolved.

We can therefore eliminate the ndo entry point into the driver and
simplify the code, making it similar to the FIB reflection, which is
based solely on events. This also helps us avoid a locking issue, in
which the RIF cache was traversed without proper locking during
insertion into the neigh entry cache.

Subject: mlxsw: spectrum_router: Remove redundant check

We only add neighbour entries that are also used for nexthops to
'nexthop_neighs_list', so when iterating over this list there's no need
to check that the entry is indeed used for nexthops.

Remove the redundant check.

Subject: mlxsw: spectrum_router: Don't read 'nud_state' without lock

We periodically ask the neighbouring system to try and resolve
neighbours that are used for nexthops, but aren't currently resolved.

However, 'nud_state' is protected by the neighbour lock, so we shouldn't
access it without taking it. Instead, we can simply check the
'connected' field of the neighbour entry, which we update upon
NEIGH_UPDATE events.

Subject: sfc: don't rearm interrupts if busy polling

Since commit 364b6055738b ("net: busy-poll: return busypolling status
to drivers"), napi_complete_done() returns a boolean that can be used
by drivers to conditionally rearm interrupts.

Testing with a 7142 shows a small latency improvement of ~100 ns.

Subject: net/mlx5e: fix another maybe-uninitialized false-positive

In commit abeffce ("net/mlx5e: Fix a -Wmaybe-uninitialized warning"), I fixed a
gcc warning for the ipv4 offload handling. Now we get the same warning for the
added ipv6 support:

drivers/net/ethernet/mellanox/mlx5/core/en_tc.c:815:40: warning: 'out_dev' may be used uninitialized in this function [-Wmaybe-uninitialized]

We can apply the same workaround here as well.

Subject: net: qcom/emac: add ethool support for setting pause parameters

To support setting the pause parameters, the driver can no longer just
mirror the PHY.  The set_pauseparam feature allows the driver to
force the setting in the MAC, regardless of how the PHY is configured.
This means that we now need to maintain an internal state for pause
frame support, and so get_pauseparam also needs to be updated.

If the interface is already running when the setting is changed, then
the interface is reset.

Note that if the MAC is configured to enable RX pause frame support
(i.e. it transmits pause frames to throttle the other end), but the
PHY is configured to block those frames, then the feature will not work.

Also some buffer size initialization code into emac_init_adapter(),
so that it lives with similar code, including the initializtion of
pause frame support.

From 6bb19474391d17954fee9a9997ecca25b35dfd46 Mon Sep 17 00:00:00 2001
From: Michael Chan <michael.chan@broadcom.com>
Date: Mon, 6 Feb 2017 16:55:32 -0500
Subject: bnxt_en: Refactor rx SKB function.

Minor refactoring of bnxt_rx_skb() so that it can easily be replaced by
a new function that handles packets in a single page.  Also, use a
function pointer bp->rx_skb_func() to switch to a new function when
we add the new mode in the next patch.

Add a new field data_ptr that points to the packet data in the
bnxt_sw_rx_bd structure.  The original data field is changed to void
pointer so that it can either hold the kmalloc'ed data or a page
pointer.

The last parameter of bnxt_rx_skb() which was the length parameter is
changed to include the payload offset of the packet in the upper 16 bit.
The offset is needed to support the rx page mode and is not used in
this existing function.

v3: Added a new data_ptr parameter to bp->rx_skb_func().  The caller
has the option to modify the starting address of the packet.  This
will be needed when XDP with headroom support is added.

v2: Changed the name of the last parameter to offset_and_len to make the
code more clear.

Subject: bnxt_en: Don't use DEFINE_DMA_UNMAP_ADDR to store DMA address in RX
 path.

To support XDP_TX, we need the RX buffer's DMA address to transmit the
packet.  Convert the DMA address field to a permanent field in
bnxt_sw_rx_bd.

Subject: bnxt_en: Add bp->rx_dir field for rx buffer DMA direction.

When driver is running in XDP mode, rx buffers are DMA mapped as
DMA_BIDIRECTIONAL.  Add a field so the code will map/unmap rx buffers
according to this field.

Subject: bnxt_en: Parameterize RX buffer offsets.

Convert the global constants BNXT_RX_OFFSET and BNXT_RX_DMA_OFFSET to
device parameters.  This will make it easier to support XDP with
headroom support which requires different RX buffer offsets.

Subject: bnxt_en: Add RX page mode support.

This mode is to support XDP.  In this mode, each rx ring is configured
with page sized buffers for linear placement of each packet.  MTU will be
restricted to what the page sized buffers can support.

Subject: bnxt_en: Use event bit map in RX path.

In the current code, we have separate rx_event and agg_event parameters
to keep track of rx and aggregation events.  Combine these events into
an u8 event mask with different bits defined for different events.  This
way, it is easier to expand the logic to include XDP tx events.

Subject: bnxt_en: Centralize logic to reserve rings.

Currently, bnxt_setup_tc() and bnxt_set_channels() have similar and
duplicated code to check and reserve rx and tx rings.  Add a new
function bnxt_reserve_rings() to centralize the logic.  This will
make it easier to add XDP_TX support which requires allocating a
new set of TX rings.

Also, the tx ring checking logic in bnxt_setup_msix() can be removed.
The rings have been reserved before hand.

Subject: bnxt_en: Add tx ring mapping logic.

To support XDP_TX, we need to add a set of dedicated TX rings, each
associated with the NAPI of an RX ring.  To assign XDP rings and regular
rings in a flexible way, we add a bp->tx_ring_map[] array to do the
remapping.  The netdev txq index is stored in the new field txq_index
so that we can retrieve the netdev txq when handling TX completions.
In this patch, before we introduce XDP_TX, the mapping is 1:1.

v2: Fixed a bug in bnxt_tx_int().

Subject: bnxt_en: Add a set of TX rings to support XDP.

Add logic for an extra set of TX rings for XDP.  If enabled, this
set of TX rings equals the number of RX rings and shares the same
IRQ as the RX ring set.  A new field bp->tx_nr_rings_xdp is added
to keep track of these TX XDP rings.  Adjust all other relevant functions

Subject: bnxt_en: Refactor tx completion path.

XDP_TX requires a different function to handle completion.  Add a
function pointer to handle tx completion logic.  Regular TX rings
will be assigned the current bnxt_tx_int() for the ->tx_int()
function pointer.

Subject: bnxt_en: Add basic XDP support.

Add basic ndo_xdp support to setup and query program, configure the NIC
to run in rx page mode, and support XDP_PASS, XDP_DROP, XDP_ABORTED
actions only.

v3: Pass modified offset and length to stack for XDP_PASS.
    Remove Kconfig option.

v2: Added trace_xdp_exception()
    Added dma_syncs.
    Added XDP headroom support.

From 38413406277fd060f46855ad527f6f8d4cf2652d Mon Sep 17 00:00:00 2001
From: Michael Chan <michael.chan@broadcom.com>
Date: Mon, 6 Feb 2017 16:55:43 -0500
Subject: bnxt_en: Add support for XDP_TX action.

Add dedicated transmit function and transmit completion handler for
XDP.  The XDP transmit logic and completion logic are different than
regular TX ring.  The TX buffer is recycled back to the RX ring when
it completes.

v3: Improved the buffer recyling scheme for XDP_TX.

v2: Add trace_xdp_exception().
    Add dma_sync.

Subject: net: ethernet: ti: cpsw: remove netif_trans_update

No need to update jiffies in txq->trans_start twice, it's supposed to be
done in netdev_start_xmit() and anyway is re-written. Also, no reason to
update trans time in case of an error.

Subject: net: netcp: Do not clobber PHY link outside of state machine

Calling phy_read_status() means that we may call into
genphy_read_status() which in turn will use genphy_update_link() which
can make changes to phydev->link outside of the state machine's state
transitions. This is an invalid behavior that is now caught as off
811a919135b9 ("phy state machine: failsafe leave invalid RUNNING state")

This bug is harmless because it's just a sanity check and we always
pass valid values for "encap_type" but the test is off by one.

We move this driver to new api {get|set}_link_ksettings.

As I don't have the hardware, I'd be very pleased if
someone may test this patch.

seems to speak about the number of RX CRC done, but in fact it is about
errors.

This patch rename it to rx_crc_errors, just like the same ifconfig
counter.

Subject: mlxsw: acl: Fix mlxsw_afa_block_commit error path

No rollback is needed since the chain is in consistent state and
mlxsw_afa_block_destroy() will take care of putting it away. So remove
the one we have now which is wrong. Also move the set of 'finished' flag
to the beginning of the function, because the block is certainly unusable
for future action addition no matter if the function succeeds or not.

When we invalidate a nexthop we should also invalidate its neighbour
entry pointer as it might be destroyed later on. This makes the nexthop
de-init function symmetric with its init and also ensures nobody will
try to access the neighbour entry.

Subject: mlxsw: spectrum_router: Store nexthop groups in a hash table

Currently, when we're notified about a new RTN_UNICAST route we perform
a lookup on the nexthop group list looking for a group with a matching
configuration to that found in the FIB info. This is quite inefficient.

Instead, we can simply rely on the kernel to consolidate several FIB
configurations into the same FIB info and use the FIB info as the key
for our private nexthop group struct.

Subject: mlxsw: spectrum_router: Store nexthops in a hash table

Later in the patchset we'll add the NH_{ADD,DEL} events which will let
us know when a nexthop is considered to be dead. Based on these events
we need to be able to add or remove the nexthop from the device's
tables.

Therefore, store the private nexthop structs in a hash table and use the
kernel's fib_nh struct as the key, so that we'll be able to easily find
them when the events are received.

Subject: mlxsw: spectrum_router: Use nexthop's scope to set action type

We currently use the scope of the FIB info to distinguish between a
direct unicast route and a gatewayed one. However, the kernel is
perfectly happy to configure a route with scope UNIVERSE to a directly
connected network.

Instead, we can rely on the first nexthop's scope to check if the route
is gatewayed or not.

Subject: mlxsw: spectrum_router: Add gateway indication to nexthop group

The next patch is going to generalize the way in which we store routes.
Instead of attaching a nexthop group only to gatewayed routes, one will
be attached to each route, in a similar way to the way the FIB code
stores its routes.

The above means that any function operating on a nexthop group cannot
assume the group represents only gatewayed nexthops. One such function
is the one that refreshes a nexthop group and updates the adjacency
table following nexthop changes.

For a nexthop group that doesn't represent any gateways this function
would essentially be a NOP, but it would be useful if it did update the
action associated with any route using it. This will allow us to later
consolidate code paths when a nexthop changes following NH_{ADD,DEL}
events.

Subject: mlxsw: spectrum_router: Store routes in a more generic way

Up until now, the only FIB entries that were associated with a nexthop
group were routes to remote networks where all the nexthop devices had a
valid router interface (RIF). This is in contrast to the FIB code,
where all the routes are associated with a FIB info. The same design
choice needs to be applied to the driver's cache.

Based on the NH_{ADD,DEL} events which will be added later in the
patchset, we need to be able to change the action (forward / trap)
associated with all the routes using the nexthop group. However, if we
can't link between the nexthop and the routes using it, then the above
is impossible.

Subject: mlxsw: spectrum_router: Remove FIB info from FIB entry struct

After the previous changes, the FIB info is embedded in every nexthop
group struct, which in turn is embedded in every FIB entry struct.

We can therefore safely remove the FIB info from the entry struct. This
has the added advantage of making the router-related structs more
generic and suitable for use with IPv6 offloads.

Subject: mlxsw: spectrum_router: Refactor nexthop init routine

The nexthop init and de-init functions both have symmetric parts
concerned with the reflection of the neighbour entry into the device's
adjacency table, in case it's used by a gatewayed route.

These sections of code also need to be called when a nexthop is marked
as valid / invalid following NH_{ADD,DEL} events. Break these out into
appropriate functions, so that they could be invoked following the
reception of above events.

Subject: mlxsw: spectrum_router: More accurately set offload flag

We currently set the RTNH_F_OFFLOAD flag for all routes using remote
action, but this isn't always correct. If none of the nexthops
associated with a gatewayed route can be offloaded into the device, then
any packet hitting it would be trapped to the CPU and forwarded by the
kernel.

Solve this by pushing the setting of the offload flag to after the route
was programmed into the device, thereby allowing us to take all the
parameters into account.

This change will also help us further in the patchset, when we refresh
routes following the reception of NH_{ADD,DEL} events.

 function

The previous patch introduced a generic function to determine whether a
route should be offloaded or not. Make use of it here.

In the future we're going to add more conditions to this test (e.g.,
whether TOS is non-zero), so it makes sense to centralize it instead of
open coding it in a few places.

Subject: mlxsw: spectrum_router: Use trap action only for some route types

The device can have one of three actions associated with a route:

1) Remote - packets continue to the adjacency table
2) Local - packets continue to the neighbour table
3) Trap - packets continue to the CPU

The first two actions can also trap packets to the CPU, but they do so
using a different trap ID, which has a lower traffic class and less
allotted bandwidth.

We currently use the third action for both RTN_{LOCAL,BROADCAST} routes
and RTN_UNICAST routes not pointing to the switch ports.

However, packets that merely need to be forwarded by the switch are
likely not control packets and can be therefore scheduled towards the
CPU using a lower traffic class.

Achieve the above by assigning the third action only to local and
broadcast routes and have any other route use either of the first two
actions, based on whether the route is gatewayed or not.

This will also allow us to refresh routes using the local action and
have them trap packets when their RIF is no longer valid following a
NH_DEL event.

One side effect of this patch is that we no longer give special
treatment to multipath routes using both switch and non-switch ports
towards their nexthops. If at least one of the nexthops can be resolved,
then the device will forward the packets instead of trapping them.

Subject: mlxsw: spectrum_router: Reflect nexthop status changes

When a packet hits a multipath route in the device's routing table, a
hash is computed over its headers, which is then used to select the
appropriate nexthop from the device's adjacency table.

There are situations in which the kernel removes a nexthop from a
multipath route (e.g., no carrier) and the device should do the same.

Upon the reception of NH_{ADD,DEL} events, add or remove a nexthop from
the device's adjacency table and refresh all the routes using the
nexthop group. If all the nexthops of a multipath route are invalid,
then any packet hitting the route would be trapped to the CPU for
forwarding.

If all the nexthops are DEAD, then the kernel would remove the route
entirely. On the other hand, if all the nexthops are merely LINKDOWN,
then the kernel would keep the route and forward any incoming packet
using a different route.

While the last case might sound like a problem, it's expected that a
routing daemon running in user space would remove such a route from the
FIB as it's dumped with the DEAD flag set.

Subject: mlxsw: spectrum_router: Flush resources when RIF is deleted

When the last IP address is removed from a netdev, its RIF is deleted.
However, if user didn't first remove neighbours and nexthops using this
interface, then they would still be present in the device's tables.

Therefore, whenever a RIF is deleted, make sure all the neighbours and
nexthops (adjacency entries) using it are removed from the relevant
tables as well.

The action associated with any route using this RIF would be refreshed,
most likely to trap. If the kernel decides to remove the route (f.e.,
because all the nexthops are now DEAD), then an event would be sent,
causing the route to be removed from the device.

Subject: mlxsw: spectrum_router: Don't reflect LINKDOWN nexthops

The kernel resolves the nexthops for a given route using
FIB_LOOKUP_IGNORE_LINKSTATE which means a notification can be sent for a
route with one of its nexthops being LINKDOWN.

In case IGNORE_ROUTES_WITH_LINKDOWN is set for the nexthop netdev, then
we shouldn't reflect the nexthop to the device's table.

Once the nexthop netdev's carrier goes up we'll be notified using NH_ADD
and reflect it to the device.

Subject: sfc: process RX event inner checksum flags

Add support for RX checksum offload of encapsulated packets. This
 essentially just means paying attention to the inner checksum flags
 in the RX event, and if *either* checksum flag indicates a fail then
 don't tell the kernel that checksum offload was successful.
Also, count these checksum errors and export the counts to ethtool -S.

Test the most common "good" case of RX events with a single bitmask
 instead of a series of ifs.  Move the more specific error checking
 in to a separate function for clarity, and don't use unlikely() there
 since we know at least one of the bits is bad.

This function wasn't being called in this particular case when the MC

 and often ended up disabling the interface.

Subject: sfc: configure UDP tunnel offload ports

Implement ndo_udp_tunnel_{add,del} to update the NIC's list of VXLAN and
 GENEVE UDP ports.  Also reset the port list to empty on driver load and
 on driver unload, with appropriate flag set on the unload case.
These port numbers are used for RX inner checksum offload, and in future
 will also be used for TX inner checksum offload and encapsulated TSO.

Subject: net: qcom/emac: add ethtool support for reading hardware registers

Implement the get_regs_len and get_regs ethtool methods.  The driver
returns the values of selected hardware registers.

The make the register offsets known to emac_ethtool, the the register
offset macros are all combined into one header file.  They were
inexplicably and arbitrarily split between two files.

Subject: net: qcom/emac: add ethtool support for setting ring parameters

Implement the set_ringparam method, which allows the user to specify
the size of the TX and RX descriptor rings.  The values are constrained
to the limits of the hardware.

Since the driver does not use separate queues for mini or jumbo frames,
attempts to set those values are rejected.

If the interface is already running when the setting is changed, then
the interface is reset.

Subject: enic: add devcmds for vxlan offload

This patch adds devcmds needed for vxlan offload. Implement 3 new devcmd

overlay_offload_ctrl: enable/disable offload
overlay_offload_cfg: update offload udp port number
get_supported_feature_ver: get hw supported offload version. Each
			   version has different bitmap for csum_ok/encap

Subject: enic: add udp_tunnel ndo for vxlan offload

Defines enic_udp_tunnel_add/del for configuring vxlan tunnel offload.
enic supports offload of only one ipv4/udp port.

There are two modes that fw supports for vxlan offload.

mode 0: fcoe bit is set for encapsulated packet. fcoe_fc_crc_ok is set
if checksum of csum is ok. This bit is or of ip_csum_ok and
tcp_udp_csum_ok

mode 2: BIT(0) in rss_hash is set if it is encapsulated packet.
	BIT(1) is set if outer_ip_csum_ok/
	BIT(2) is set if outer_tcp_csum_ok

tcp_udp_csum_ok/ipv4_csum_ok is set if inner csum is OK.

Subject: net/ena: fix queues number calculation

The ENA driver tries to open a queue per vCPU.
To determine how many vCPUs the instance have it uses num_possible_cpus()
while it should have use num_online_cpus() instead.

Subject: net/ena: fix ethtool RSS flow configuration

ena_flow_data_to_flow_hash and ena_flow_hash_to_flow_type
treat the ena_flow_hash_to_flow_type enum as power of two values.

Change the values of ena_admin_flow_hash_fields to be power of two values.

This bug effect the ethtool set/get rxnfc.
ethtool will report wrong values hash fields for get and will
configure wrong hash fields in set.

Subject: net/ena: fix NULL dereference when removing the driver after device
 reset failed

If for some reason the device stops responding, and the device reset
failes to recover the device, the mmio register read data structure
will not be reinitialized.

On driver removal, the driver will also try to reset the device, but
this time the mmio data structure will be NULL.

To solve this issue, perform the device reset in the remove function
only if the device is runnig.

Subject: net/ena: refactor ena_get_stats64 to be atomic context safe

ndo_get_stat64() can be called from atomic context, but the current
implementation sends an admin command to retrieve the statistics from
the device. This admin command can sleep.

This patch re-factors the implementation of ena_get_stats64() to use
the {rx,tx}bytes/count from the driver's inner counters, and to obtain
the rx drop counter from the asynchronous keep alive (heart bit)
event.

Subject: net/ena: fix potential access to freed memory during device reset

If the ena driver detects that the device is not behave as expected,
it tries to reset the device.
The reset flow calls ena_down, which will frees all the resources
the driver allocates and then it will reset the device.

This flow can cause memory corruption if the device is still writes
to the driver's memory space.
To overcome this potential race, move the reset before the device
resources are freed.

Subject: net/ena: change condition for host attribute configuration

Move the host info config to be the first admin command that is executed.
This change require the driver to remove the 'feature check'
from host info configuration flow.
The check is removed since the supported features bitmask field
is retrieved only after calling ENA_ADMIN_DEVICE_ATTRIBUTES admin command.

If set host info is not supported an error will be returned by the device.

Subject: mlxsw: spectrum_router: Correctly handle identical routes

In the device, routes are indexed in a routing table based on the prefix
and its length. This is in contrast to the kernel's FIB where several
FIB aliases can exist with these parameters being identical. In such
cases, the routes will be sorted by table ID (LOCAL first, then MAIN),
TOS and finally priority (metric).

During lookup, these routes will be evaluated in order. In case the
packet's TOS field is non-zero and a FIB alias with a matching TOS is
found, then it's selected. Otherwise, the lookup defaults to the route
with TOS 0 (if it exists). However, if the requested scope is narrower
than the one found, then the lookup continues.

To best reflect the kernel's datapath we should take the above into
account. Given a prefix and its length, the reflected route will always
be the first one in the FIB alias list. However, if the route has a
non-zero TOS then its action will be converted to trap instead of
forward, since we currently don't support TOS-based routing. If this
turns out to be a real issue, we can add support for that using
policy-based switching.

The route's scope can be effectively ignored as any packet being routed
by the device would've been looked-up using the widest scope (UNIVERSE).

To achieve that we need to do two changes. Firstly, we need to create
another struct (FIB node) that will hold the list of FIB entries sharing
the same prefix and length. This struct will be hashed using these two
parameters.

Secondly, we need to change the route reflection to match the above
logic, so that the first FIB entry in the list will be programmed into
the device while the rest will remain in the driver's cache in case of
subsequent changes.

Subject: mlxsw: spectrum_router: Add support for route append

When a new route is appended, it's placed after existing routes sharing
the same parameters (prefix, length, table ID, TOS and priority).

While the device supports only one route with the same prefix and length
in a single table, it's important to correctly place the appended route
in the driver's cache, as when a route is deleted the next one is
programmed into the device.

Following the reception of an ENTRY_APPEND notification, resolve the
FIB node corresponding to the prefix and length and correctly place the
new entry in its entry list.

Subject: mlxsw: spectrum_router: Add support for route replace

Upon the reception of an ENTRY_REPLACE notification, resolve the FIB
node corresponding to the prefix and length and insert the new route
before the first matching entry.

Since the notification also signals the deletion of the replaced route,
delete it from the driver's cache.

Subject: mlxsw: spectrum: Break flood set func to be per table

Currently, the flood set function can't operate on only one table, but
sets both uc_flood and mb_flood together.
This patch creates a function that sets the flood state per table.

Subject: mlxsw: spectrum: Change max vfid

A user that wants many bridges will use 1.Q bridge which are scalable.
One can have as many 1.Q bridges as vfids.
This patch sets their number to 1k, which is a reasonably large number.
This change is done here because the next patches will add a new flood
table, and without it, it will increase the overall size of the flood
tables dramatically.

Subject: mlxsw: spectrum: Separate bc and mc floods

Break the bm (broadcast-multicast) into two tables, one for broadcast
(and link local multicast that behaves like bc) and one for unknown
multicasts.
Add a bool into mlxsw_sp_port named mc_flood that reflect the value this
port should have in the mc flood table (currently, always 1);

Subject: mlxsw: spectrum: Add an option to flood mc by mc_router_port

The decision whether to flood a multicast packet to a port dependent
on three flags: mc_disabled, mc_router_port, mc_flood.

If mc_disabled is on, the port will be flooded according to mc_flood,
otherwise, according to mc_router_port. To accomplish that, add those
flags into the mlxsw_sp_port struct and update the mc flood table
accordingly.

Update mc_router_port by switchdev attribute
SWITCHDEV_ATTR_ID_PORT_MC_ROUTER_PORT.

Subject: mlxsw: spectrum: Extend port_orig_get for bridge devices

The function mlxsw_sp_port_orig_get returns the vport from the physical
port if needed, based on the original device.
This patch addresses the case where the original device is a bridge.
If it is vlan unaware bridge, it returns the matching vport. If it is vlan
aware bridge, there is no matching vport, and it returns the original port.

HW does not understand ETH_P_ALL. So treat this special case differently
and translate to 0/0 key/mask. That will allow HW to match all ethertypes.

Subject: nfp: rename the driver and add new main file

Support for the PF driver is about to be added and will share
much of the code.  When the VF driver was added we planned to
maintain the PF driver as a separate module but have decided
that for our simple use case just maintaining a single module
is more reasonable.  Rename the driver to just "nfp" and update
the Kconfig.

While at it remove latent references to NFP3200.

From 4cb584e0ee7df70fd0376aee60cf701855ea8c81 Mon Sep 17 00:00:00 2001
From: Jakub Kicinski <jakub.kicinski@netronome.com>
Date: Thu, 9 Feb 2017 09:17:29 -0800
Subject: nfp: add CPP access core

Command Push Pull is the name of NFP's network on a chip.
PCIe PF can access the interconnect through a number of mappings
controlled via Base Access Registers.  BARs allow the PF to issue
pretty much any command or address any memory on the chip.

Add appropriate logic and a handful of helper for simple operations
like reading scalars from memories.

Subject: nfp: allocate irqs in lower driver

PF services multiple ports using single PCI device therefore
IRQs can no longer be allocated in the netdev code.  Lower
portion of the driver has to allocate the IRQs and hand them
out to ports.

If skb_padto failed the skb has been dropped already, so it was
consumed, but it doesn't mean it was sent, thus no need to update
queue tx time, etc. So, return NET_XMIT_DROP as more appropriate.

Subject: i40e/i40evf: Limit DMA sync of RX buffers to actual packet size

On packet RX, we perform a DMA sync for CPU before passing the
packet up.  Here we limit that sync to the actual length of the
incoming packet, rather than always syncing the entire buffer.

Subject: i40e/i40evf: Moves skb from i40e_rx_buffer to i40e_ring

This patch reduces the size of struct i40e_rx_buffer by one pointer,
and makes the i40e driver a little more consistent with the igb driver
in terms of packets that span buffers.

We do this by moving the skb field from struct i40e_rx_buffer to
struct i40e_ring. We pass the skb we already have (or NULL if we
don't) to i40e_fetch_rx_buffer(), which skips the skb allocation if we
already have one for this packet.

Subject: i40e/i40evf: eliminate i40e_pull_tail()

Reorganize the i40e_pull_tail() logic, doing it in i40e_add_rx_frag()
where it's cheaper.  The igb driver does this the same way.

Also renames i40e_page_is_reserved() to reflect what it actually
tests.

Subject: i40e: update comment explaining where FDIR buffers are freed

The original comment implies that the only location where the raw_packet
buffer will be freed is in i40e_clean_tx_ring() which is incorrect. In
fact this isn't even the normal case. Update the comment explaining
where the memory is freed.

Subject: i40e: don't warn every time we clear an Rx timestamp register

The intent of this message was to indicate to a user that we might have
missed a timestamp event for a valid packet. The original method of
detecting the missed events relied on waiting until all 4 registers were
filled.

A recent commit d55458c0cd7a5 ("i40e: replace PTP Rx timestamp hang
logic") replaced this logic with much better detection
scheme that could detect a stalled Rx timestamp register even when other
registers were still functional.

The new logic means that a message will be displayed almost as soon as
a timestamp for a dropped frame occurs. This new logic highlights that
the hardware will attempt timestamp for frames which it later decides to
drop. The most prominent example is when a multicast PTP frame is
received on a multicast address that we are not subscribed to.

Because the hardware initiates the Rx timestamp as soon as possible, it
will latch an RXTIME register, but then drop the packet.

This results in users being confused by the message as they are not
expecting to see dropped timestamp messages unless their application
also indicates that timestamps were missing.

Resolve this by reducing the severity and frequency of the displayed
message. We now only print the message if 3 or 4 of the RXTIME registers
are stalled and get cleared within the same watchdog event. This ensures
that the common case does not constantly display the message.
Additionally, since the message is likely not as meaningful to most
users, reduce the message to a dev_dbg instead of a dev_warn.

Users can still get a count of the number of timestamps dropped by
reading the ethtool statistics value, if necessary.

Subject: i40e: allow i40e_update_filter_state to skip broadcast filters

Fix a bug where we modified the mac_filter_hash while outside a lock,
when handling addition of broadcast filters.

Normally, we add filters to firmware by batching the additions into
lists and issuing 1 update for every few filters. Broadcast filters are
handled differently, by instead setting the broadcast promiscuous mode
flags. In order to make sure the 1<->1 mapping of filters in our
addition array lined up with filters in the hlist tmp_add_list, we had
to remove the filter and move it back to the main hash. However, we
didn't do this under lock, which could cause consistency problems for
the list.

Fix this by updating i40e_update_filter_state logic so that it knows to
avoid broadcast filters. This ensures that we don't have to remove the
filter separately, and can put it back using the normal flow.

Subject: i40e: avoid race condition when sending filters to firmware for
 addition

Refactor how we add new filters to firmware to avoid a race condition
that can occur due to removing filters from the hash temporarily.

To understand the race condition, suppose that you have a number of MAC
filters, but have not yet added any VLANs. Now, add two VLANs in rapid
succession. A possible resulting flow would look something like the
following:

(1) lock hash for add VLAN
(2) add the new MAC/VLAN combos for each current MAC filter
(3) unlock hash
(4) lock hash for filter sync
(5) notice that we have a VLAN, so prepare to update all MAC filters
    with VLAN=-1 to be VLAN=0.
(6) move NEW and REMOVE filters to temporary list
(7) unlock hash
(8) lock hash for add VLAN
(9) add new MAC/VLAN combos. Notice that no MAC filters are currently in
    the hash list, so we don't add any VLANs <--- BUG!
(10) unlock hash
(11) sync the temporary lists to firmware
(12) lock hash for post-sync
(13) move the temporary elements back to the main list
....

Because we take filters out of the main hash into temporary lists, we
introduce a narrow window where it is possible that other callers to the
list will not see some of the filters which were previously added but
have not yet been finalized. This results in sometimes dropping VLAN
additions, and could also result in failing to add a MAC address on the
newly added VLAN.

One obvious way to avoid this race condition would be to lock the entire
firmware process. Unfortunately this does not work because adminq
firmware commands take a mutex which results in a sleep while atomic
BUG(). So, we can't use the simplest approach.

An alternative approach is to simply not remove the filters from the
hash list while adding. Instead, add an i40e_new_mac_filter structure
which we will use to track added filters. This avoids the need to remove
the filter from the hash list. We'll store a pointer to the original
i40e_mac_filter, along with our own copy of the state.

We won't update the state directly, so as to avoid race with other code
that may modify the state while under the lock. We are safe to read
f->macaddr and f->vlan since these only change in two locations. The
first is on filter creation, which must have already occurred. The
second is inside i40e_correct_vlan_filters which was previously run
after creation of this object and can't be run again until after. Thus,
we should be safe to read the MAC address and VLAN while outside the
lock.

We also aren't going to run into a use-after-free issue because the only
place where we free filters is when they are marked FAILED or when we
remove them inside the sync subtask. Since the subtask has its own
critical flag to prevent duplicate runs, we know this won't happen. We
also know that the only location to transition a filter from NEW to
FAILED is inside the subtask also, so we aren't worried about that
either.

Use the wrapper i40e_new_mac_filter for additions, and once we've
finalized the addition to firmware, we will update the filter state
inside a lock, and then free the wrapper structure.

In order to avoid a possible race condition with filter deletion, we
won't update the original filter state unless it is still
I40E_FILTER_NEW when we finish the firmware sync.

This approach is more complex, but avoids race conditions related to
filters being temporarily removed from the list. We do not need the same
behavior for deletion because we always unconditionally removed the
filters from the list regardless of the firmware status.

Subject: bnxt_en: Retry failed NVM_INSTALL_UPDATE with defragmentation flag.

If the HWRM_NVM_INSTALL_UPDATE command fails with the error code
NVM_INSTALL_UPDATE_CMD_ERR_CODE_FRAG_ERR, retry the command with
a new flag to allow defragmentation.  Since we are checking the
response for error code, we also need to take the mutex until
we finish reading the response.

Subject: bnxt_en: Fix ethtool -l pre-set max combined channel.

With commit d1e7925e6d80 ("bnxt_en: Centralize logic to reserve rings."),
ring allocation for combined rings has become stricter.  A combined
ring must now have an rx-tx ring pair.  The pre-set max. for combined
rings should now be min(rx, tx).

Fixes: d1e7925e6d80 ("bnxt_en: Centralize logic to reserve rings.")

Commit ae10ae740ad2 ("bnxt_en: Add new hardware RFS mode.") has added

Subject: bnxt_en: Do not setup PHY unless driving a single PF.

If it is a VF or an NPAR function, the firmware call to setup the PHY
will fail.  Adding this check will prevent unnecessary firmware calls
to setup the PHY unless calling from the PF.  This will also eliminate
many unnecessary warning messages when the call from a VF or NPAR fails.

Subject: net: micrel: ksz884x: use new api ethtool_{get|set}_link_ksettings

The ethtool api {get|set}_settings is deprecated.
We move this driver to new api {get|set}_link_ksettings.

As I don't have the hardware, I'd be very pleased if
someone may test this patch.

Subject: net: micrel: ks8851_mll: use new api ethtool_{get|set}_link_ksettings

The ethtool api {get|set}_settings is deprecated.
We move this driver to new api {get|set}_link_ksettings.

As I don't have the hardware, I'd be very pleased if
someone may test this patch.

Subject: net:ethernet:aquantia: Add 2500/5000 mbit link modes support.

Using new link mode indices instead deprecated SUPPORTED_/ADVERTISED_
macro.

Added indication for 2500 and 5000mbit link modes (AQtion adapter already
supports these speeds).

Subject: net/mlx5: Consolidate flow rules regardless their flow tag

Flow rules with same match criteria and value should be mapped to
the same flow table entry regardless the flow tag identifier.

Flow tag is part of flow table entry context and not of the
destination, therefore we should return error when we try to add
destination to flow table entry with different flow tag.

Subject: sunvnet: make sunvnet common code dynamically loadable

When the sunvnet_common code was split out for use by both sunvnet
and the newer ldmvsw, it was made into a static kernel library, which
limits the usefulness of sunvnet and ldmvsw as loadables, since most
of the real work is being done in the shared code.  Also, this is
simply dead code in kernels that aren't running the LDoms.

This patch makes the sunvnet_common into a dynamically loadable
module and makes sunvnet and ldmvsw dependent on sunvnet_common.

Subject: sunvnet: remove unused variable in maybe_tx_wakeup

The vio_dring_state *dr variable is unused in maybe_tx_wakeup().
As the comments indicate, we call maybe_tx_wakeup() whenever we
get a STOPPED LDC message on the port. If the queue is stopped,
we want to wake it up so that we will send another START message
at the next TX and trigger the consumer to drain the dring.

Subject: ldmvsw: disable tso and gso for bridge operations

The ldmvsw driver is specifically for supporting the ldom virtual
networking by running in the primary ldom and using the LDC to connect
the remaining ldoms to the outside world via a bridge.  With TSO and GSO
supported while connected the bridge, things tend to misbehave as seen
in our case by delayed packets, enough to begin triggering retransmits
and affecting overall throughput.  By turning off advertised support for
TSO and GSO we restore stable traffic flow through the bridge.

Subject: pcnet32: fix BNC/AUI port on AM79C970A

Even though the port autoselection is enabled by default on AM79C970A,
BNC/AUI port does not work because the link is always reported to be
down. The link state reported by the chip belongs only to the TP port
but the driver uses it regardless of the port used. The chip can't
detect BNC/AUI link state.

Disable port autoselection and use TP port by default to keep current
behavior (link detection works on TP port, BNC/AUI port does not work).

Implement ethtool autoneg, port and duplex configuration to allow
using the BNC/AUI port.

Report the TP link state only if the TP port is selected. When the
port autoselection is enabled or AUI port is selected, report the link
as always up.

Move pcnet32_suspend() and pcnet32_clr_suspend() functions to avoid
forward declarations.

Subject: net: ethernet: ti: cpsw: use var instead of func for usage count

The usage count function is based on ndev_running flag that is
updated before calling ndo_open/close, but if ndo is called in
another place, as with suspend/resume, the counter is not changed,
that breaks sus/resume. For common resource no difference which
device is using it, does matter only device count. So, replace
usage count function on var and inc and dec it in ndo_open/close.

Subject: mlx4: do not use rwlock in fast path

Using a reader-writer lock in fast path is silly, when we can
instead use RCU or a seqlock.

For mlx4 hwstamp clock, a seqlock is the way to go, removing
two atomic operations and false sharing.

Subject: qede: Add driver support for PTP

This patch adds the driver support for,
  - Registering the ptp clock functionality with the OS.
  - Timestamping the Rx/Tx PTP packets.
  - Ethtool callbacks related to PTP.

Subject: net: ethernet: aquantia: switch to pci_alloc_irq_vectors

pci_enable_msix has been long deprecated, but this driver adds a new
instance.  Convert it to pci_alloc_irq_vectors so that no new instance
of the deprecated function reaches mainline.

The stmmac_adjust_link() function is called too rarely for having
likely() macros being useful.
Just remove likely annotation in it.

Subject: net: stmmac: use SPEED_UNKNOWN/DUPLEX_UNKNOWN

It is better to use DUPLEX_UNKNOWN instead of just "-1".
Using 0 for an invalid speed is bad since 0 is a valid value for speed.
So this patch replace 0 by SPEED_UNKNOWN.

Subject: net: stmmac: set speed at SPEED_UNKNOWN in case of broken speed

In case of invalid speed given, stmmac_adjust_link() still record it as
current speed.
This patch modify the default case to set speed as SPEED_UNKNOWN if not
10/100/1000.

Subject: mlxsw: acl: Use PBS type for forward action

Current behaviour of "mirred redirect" action (forward) offload is a bit
odd. For matched packets the action forwards them to the desired
destination, but it also lets the packet duplicates to go the original
way down (bridge, router, etc). That is more like "mirred mirror".
Fix this by using PBS type which behaves exactly like "mirred redirect".
Note that PBS does not support loopback mode.

Subject: ixgbe: Add function for checking to see if we can reuse page

This patch consolidates the code for the ixgbe driver so that it is more
inline with what is already in igb.  The general idea is to just
consolidate functions that represent logical steps in the Rx process so we
can later update them more easily.

Subject: ixgbe: Only DMA sync frame length

On some platforms, syncing a buffer for DMA is expensive. Rather than
sync the whole 2K receive buffer, only synchronise the length of the
frame, which will typically be the MTU, or a much smaller TCP ACK.

Subject: ixgbe: Update driver to make use of DMA attributes in Rx path

This patch adds support for DMA_ATTR_SKIP_CPU_SYNC and
DMA_ATTR_WEAK_ORDERING.  By enabling both of these for the Rx path we are
able to see performance improvements on architectures that implement either
one due to the fact that page mapping and unmapping only has to sync what
is actually being used instead of the entire buffer.  In addition by
enabling the weak ordering attribute enables a performance improvement for
architectures that can associate a memory ordering with a DMA buffer such
as Sparc.

Subject: ixgbe: Update code to better handle incrementing page count

Batch the page count updates instead of doing them one at a time.  By doing
this we can improve the overall performance as the atomic increment
operations can be expensive due to the fact that on x86 they are locked
operations which can cause stalls.  By doing bulk updates we can
consolidate the stall which should help to improve the overall receive
performance.

Subject: ixgbe: Make use of order 1 pages and 3K buffers independent of FCoE

In order to support build_skb with jumbo frames it will be necessary to use
3K buffers for the Rx path with 8K pages backing them.  This is needed on
architectures that implement 4K pages because we can't support 2K buffers
plus padding in a 4K page.

In the case of systems that support page sizes larger than 4K the 3K
attribute will only be applied to FCoE as we can fall back to using just 2K
buffers and adding the padding.

Subject: ixgbe: Use length to determine if descriptor is done

This change makes it so that we use the length of the packet instead of the
DD status bit to determine if a new descriptor is ready to be processed.
The obvious advantage is that it cuts down on reads as we don't really even
need the DD bit if going from a 0 to a non-zero value on size is enough to
inform us that the packet has been completed.

Subject: ixgbe: Break out Rx buffer page management

We are going to be expanding the number of Rx paths in the driver.  Instead
of duplicating all that code I am pulling it apart into separate functions
so that we don't have so much code duplication.

Subject: ixgbe: Add support for padding packet

This patch adds support for providing a buffer with headroom and tailroom
to allow for shared info, NET_SKB_PAD, and NET_IP_ALIGN.  With this
combined with the DMA changes we can start using build_skb to build frames
around an incoming Rx buffer instead of having to memcpy the headers.

Subject: ixgbe: Add private flag to control buffer mode

Since there are potential drawbacks to the new Rx allocation approach I
thought it best to add a "chicken bit" so that we can turn the feature off
if in the event that a problem is found.

It also provides a means of validating the legacy Rx path in the event that
we are forced to fall back.  At some point in the future when we are
convinced we don't need it anymore we might be able to drop the legacy-rx
flag.

Subject: ixgbe: Add support for build_skb

This patch adds build_skb support to the Rx path.  There are several
advantages to this change.

1.  It avoids the memcpy and skb->head allocation for small packets which
    improves performance by about 5% in my tests.
2.  It avoids the memcpy, skb->head allocation, and eth_get_headlen
    for larger packets improving performance by about 10% in my tests.
3.  For VXLAN packets it allows the full header to be in skb->data which
    improves the performance by as much as 30% in some of my tests.

Subject: ixgbe: Don't bother clearing buffer memory for descriptor rings

This patch makes it so that we don't need to bother with clearing the
memory out for the descriptor rings.  The general idea is to only free
buffers associated with buffers in use which are located between the
next_to_clean and next_to_use or next_to_alloc values.  Everything outside
of those regions can be safely ignored since they should have no buffers
associated with them.

The advantage to doing things this way is that is should speed up bring-up
and tear-down of the rings.  Specifically we can avoid the 512 or more
cycles required to memset the rings in tear-down.  In the bring-up phase we
then clear the memory as a part of initialization.  The general idea is
that the clearing in initialization can act as a prefetch of sorts for the
buffer info structures so they are in the local CPU when we go to populate
them.  This should help to improve overall time needed to perform a
suspend/resume.

But mlx4_eq_int() also fires a tasklet to service all items that were
queued via mlx4_add_cq_to_tasklet(), but this handler was not called
unless user cqe was handled.

This is very confusing, as "mpstat -I SCPU ..." show huge number of
tasklet invocations.

This patch saves this overhead, by carefully firing the tasklet directly
from mlx4_add_cq_to_tasklet(), removing four atomic operations per IRQ.

Subject: net: nvidia: forcedeth: use new api ethtool_{get|set}_link_ksettings

The ethtool api {get|set}_settings is deprecated.
We move this driver to new api {get|set}_link_ksettings.

As I don't have the hardware, I'd be very pleased if
someone may test this patch.

Subject: net: ethoc: Use eth_hw_addr_random()

Use eth_hw_addr_random() to set a random dev_addr and update
addr_assign_type instead of open-coding it.

Subject: net: bgmac: store MAC address directly in netdev->dev_addr

After commit 34a5102c3235 ("net: bgmac: allocate struct bgmac just once
& don't copy it") the mac_addr member of struct bgmac is no longer
necessary to pass the MAC address to bgmac_enet_probe(). Instead it can
directly be stored in netdev->dev_addr.

Also use eth_hw_addr_random() instead of eth_random_addr() in case a
random MAC is nedded. This will make sure netdev->addr_assign_type will
be properly set.

The ethtool api {get|set}_settings is deprecated.
We move this driver to new api {get|set}_link_ksettings.

As I don't have the hardware, I'd be very pleased if
someone may test this patch.

Subject: nfp: Use PCI_DEVICE_ID_NETRONOME_NFP* defines

Use PCI_DEVICE_ID_NETRONOME_NFP*, defined in linux/pci_ids.h,
rather than replicating the same values in the NFP driver.

Subject: sfc: fix filter_id misinterpretation in edge case

On EF10, hardware filter IDs are 13 bits, but in some places we store
 32-bit "full filter IDs" in which higher order bits encode the filter
 match-priority.  This could cause a filter to have a full filter ID of
 0xffff, which is also the value EFX_EF10_FILTER_ID_INVALID which we use
 in 16-bit "short" filter IDs (without match-priority bits).  This would
 occur if the hardware filter ID was 0x1fff and the match-priority was 7.
Unfortunately, some code that checks for EFX_EF10_FILTER_ID_INVALID can
 be called on full filter IDs, and will WARN_ON if this ever happens.
So, since we have plenty of spare bits in the full filter ID, this patch
 shifts the priority bits left one bit when constructing the full filter
 IDs, ensuring that the 0x2000 bit of a full filter ID will always be 0
 and thus no full filter ID can ever equal EFX_EF10_FILTER_ID_INVALID.

This patch also replaces open-coded full<->short filter ID conversions
 with calls to functions, thus keeping the definition of the full filter
 ID format in one place.

Subject: sfc: do not device_attach if a reset is pending

efx_start_all can return without initialising queues as a reset is pending.
 This means that when netif_device_attach is called, the kernel can start
 sending traffic without having an initialised TX queue to send to.
This patch avoids this by not calling netif_device_attach if there is a
 pending reset.

Fixes: e283546c0465 ("sfc:On MCDI timeout, issue an FLR (and mark MCDI to fail-fast)")

Subject: i40e: fix disable overflow promiscuous mode

There exists a bug in which the driver is unable to exit overflow
promiscuous mode after having added "too many" mac filters.  It is
expected that after triggering overflow promiscuous, removing the
failed/extra filters should then disable overflow promiscuous mode.

The bug exists because we were intentionally skipping the sync_vsi_filter
path in cases where we were removing failed filters since they shouldn't
have been added to the firmware in the first place, however we still
need to go through the sync_vsi_filter code path to determine whether or
not it is ok to exit overflow promiscuous mode.  This patch fixes the
bug by making sure we go through the sync_vsi_filter path in cases of
failed filters.

Subject: i40e: enable mc magic pkt wakeup during power down

This patch adds a call to the mac_address_write admin q function during
power down to update the PRTPM_SAH/SAL registers with the MC_MAG_EN bit
thus enabling multicast magic packet wakeup.

A FW workaround is needed to write the multicast magic wake up enable
bit in the PRTPM_SAH register. The FW expects the mac address write
admin q cmd to be called first with one of the WRITE_TYPE_LAA flags
and then with the multicast relevant flags.

*Note: This solution only works for X722 devices currently. A PFR will
clear the previously mentioned bit by default, but X722 has support for a
WOL_PRESERVE_ON_PFR flag which prevents the bit from being cleared. Once
other devices support this flag, this solution should work as well.

This call is made just prior to running i40e_link_event. In
i40e_link_event, we set hw->phy.get_link_info to true just prior to
calling i40e_get_link_status, which conveniently runs
i40e_update_link_info for us. Thus, we are running i40e_update_link_info
twice, which seems like something we don't need to do...

Subject: i40evf: free rings in remove function

When the i40evf_remove() calls netdev close, the device doesn't actually
close - it schedules the work for the watchdog to perform. Since we're
stopping the watchdog, this work doesn't get done. However, we're
resetting the part, so we can free resources after the reset request has
gone through. This plugs a memory leak.

Subject: i40e: Fix Adaptive ITR enabling

This patch fixes a bug introduced with the addition of the per queue
ITR feature support in ethtool.  With that addition, there were
functions added which converted the ITR settings to binary values.
The IS_ENABLED macros that run on those values check whether a bit
is set or not and with the value being binary, the bit check always
returned ITR disabled which prevents any updating of the ITR rate.
This patch fixes the problem by changing the functions to return the
current ITR value instead and renaming it to better reflect
its function.  These functions now provide a value which will be
accurately asessed and update the ITR as intended.

On Big Endian platforms we would incorrectly calculate the wrong switch

Subject: i40e: Error handling for link event

There exists an intermittent bug which causes the 'Link Detected'
field reported by the 'ethtool <iface>' command to be 'Yes' when
in fact, there is no link. This patch fixes the problem by
enabling temporary link polling when i40e_get_link_status returns
an error. This causes the driver to remember that an admin queue
command failed and polls, until the function returns with a success.

Subject: i40e: mark the value passed to csum_replace_by_diff as __wsum

Fix, or rather, avoid a sparse warning caused by the fact that
csum_replace_by_diff expects to receive a __wsum value. Since the
calculation appears to work, simply typecast the passed paylen value to
__wsum to avoid the warning.

This seems pretty fishy since __wsum was obviously annotated as
a separate type on purpose, so this throws the entire calculation into
question. Since it currently appears to behave as expected, the typecast
is probably safe.

The following message is logged from time to time when using i40e:
NOHZ: local_softirq_pending 08

i40e may schedule napi from a workqueue. Afterwards, softirqs are not run
in a deterministic time frame. The problem is the same as what was
described in commit ec13ee80145c ("virtio_net: invoke softirqs after
__napi_schedule") and this patch applies the same fix to i40e.

From 6c267b3dea09aebe84752cfedcab140c908830bb Mon Sep 17 00:00:00 2001
From: Thomas Falcon <tlfalcon@linux.vnet.ibm.com>
Date: Wed, 15 Feb 2017 12:17:58 -0600
Subject: ibmvnic: Handle processing of CRQ messages in a tasklet

Create a tasklet to process queued commands or messages received from
firmware instead of processing them in the interrupt handler. Note that
this handler does not process network traffic, but communications related
to resource allocation and device settings.

Subject: ibmvnic: Use common counter for capabilities checks

Two different counters were being used for capabilities
requests and queries. These commands are not called
at the same time so there is no reason a single counter
cannot be used.

Subject: ibmvnic: Make CRQ interrupt tasklet wait for all capabilities crqs

After sending device capability queries and requests to the vNIC Server,
an interrupt is triggered and the responses are written to the driver's
CRQ response buffer. Since the interrupt can be triggered before all
responses are written and visible to the partition, there is a danger
that the interrupt handler or tasklet can terminate before all responses
are read, resulting in a failure to initialize the device.

To avoid this scenario, when capability commands are sent, we set
a flag that will be checked in the following interrupt tasklet that
will handle the capability responses from the server. Once all
responses have been handled, the flag is disabled; and the tasklet
is allowed to terminate.

Subject: mlx4: fix potential divide by 0 in mlx4_en_auto_moderation()

1) In the case where rate == priv->pkt_rate_low == priv->pkt_rate_high,
mlx4_en_auto_moderation() does a divide by zero.

2) We want to properly change the moderation parameters if rx_frames
was changed (like in ethtool -C eth0 rx-frames 16)

Subject: net: ena: remove superfluous check in ena_remove()

The check in ena_remove() for the pci driver data not being NULL is not
needed, since it is always set in the probe() function. Remove the
superfluous check.

Subject: net: aquantia: remove function aq_ring_tx_deinit

Both functions aq_ring_rx_deinit() and aq_ring_tx_clean() are almost
identical aside from an additional check in the latter.
Move that check from the function into its caller and replace
aq_ring_rx_deinit() with aq_ring_rx_deinit().

By doing this also adjust the functions return value from int to void
since it can never fail.

The ethtool api {get|set}_settings is deprecated.
We move this driver to new api {get|set}_link_ksettings.

As I don't have the hardware, I'd be very pleased if
someone may test this patch.

Since mlx4 NIC are used on PowerPC with 64K pages, we need to adapt
MLX4_EN_ALLOC_PREFER_ORDER definition.

Otherwise, a fragment sitting in an out of order TCP queue can hold
0.5 Mbytes and it is a serious OOM risk.

Subject: nfp: refactor NSP initialization and add error message

When acquiring NSP communication resource fails user is left with
"probe failed with error -2" PCI code message but no info on what
caused the problem.  Some development boards may not have NSP FW
in the flash image.  Help users with a more verbouse message.

While at it move the whole NSP init to a separate function to keep
.probe() callback nice and simple.

ethtool_drvinfo->fw_version can cantain multiple FW strings.
We already report NFD ABI version there, add NSP ABI version
if available (i.e. on PF) with 'sp:' prefix.

Subject: nfp: return nfp_rtsym_read_le() errors correctly

nfp_rtsym_read_le() has an out parameter for error codes.
We have to use that instead of returning errors directly.

Subject: nfp: allow application firmware to limit number of SR-IOV VFs

Some application firmware projects may choose to limit the number
of VFs available below what is specified in PCI capability to be
able to reuse the PCIe interface resources.  There may also be
projects which use cases don't require SR-IOV support at all and
therefore don't want to spend time implementing/testing it.

Check nfd_vf_cfg_max_vfs firmware symbol to see if application
firmware is reporting how many VFs it supports.  This mechanism
is an opt-in, if symbol is not present we will only look at the
PCI capability values.

Subject: net: qlogic: qlcnic: use new api ethtool_{get|set}_link_ksettings

The ethtool api {get|set}_settings is deprecated.
We move this driver to new api {get|set}_link_ksettings.

As I don't have the hardware, I'd be very pleased if
someone may test this patch.

Subject: net: qlogic: qlge: use new api ethtool_{get|set}_link_ksettings

The ethtool api {get|set}_settings is deprecated.
We move this driver to new api {get|set}_link_ksettings.

As I don't have the hardware, I'd be very pleased if
someone may test this patch.

Subject: net: ethernet: aquantia: Fixes for aq_ndev_change_mtu

1)Removed unnecessary comparsion "old_mtu == new_mtu".
This check is not needed. Function aq_ndev_change_mtu wont be called
if mtu has not changed.

2)Removed extra assignment ndev->mtu = new_mtu;
This assignment already done inside __dev_set_mtu().

3)Use core MTU checking for min_mtu.

rxd_wb->pkt_len is the total length of the packet.
If we received a large packet (with length > AQ_CFG_RX_FRAME_MAX) then we
will get multiple buffers. We need to fix the length of the last buffer.

Subject: qed: Reflect PF link when initializing VF

VF learns of the current link state via its bulletin board,
which might reflect either the physical link state or some
user-configured logical state.
Whenever the physical link changes or whnever such a configuration
is explicitly made by user the PF driver would update the bulletin
that the VF reads. But if neither has happened - i.e., PF still
hasn't got a physical link up and no additional configuration was
done the VF wouldn't have a valid link information available.

Simply reflect the physical link state whenever the VF is
initialized. The user could then affect it however he wants.

Subject: qed: Don't allocate SBs using main PTT

Flows accessing registers require the flow to hold a PTT entry.
To protect 'major' load/unload flows a main_ptt is pre-allocated
to guarantee such flows wouldn't be blocked by PTT being
unavailable.

Status block initialization currently uses the main_ptt which
is incorrect, as this flow might run concurrently to others
[E.g., loading qedr while toggling qede]. That would have dire
effects as it means registers' access to device breaks and further
read/writes might access incorrect addresses.

Instead, when initializing status blocks acquire/release a PTT
as part of the flow.

Subject: qed*: Fix link indication race

Driver changes the link properties via communication with
the management firmware, and re-reads the resulting link status
when it receives an indication that the link has changed.
However, there are certain scenarios where such indications
might be missing, and so driver also re-reads the current link
results without attention in several places. Specifically, it
does so during load and when resetting the link.

This creates a race where driver might reflect incorrect
link status - e.g., when explicit reading of the link status is
switched by attention with the changed configuration.

Correct this flow by a lock syncronizing the handling of the
link indications [both explicit requests and attention].

If bnxt_hwrm_ring_free() is called during a failure path in bnxt_open(),
it is possible that the completion rings have not been allocated yet.
In that case, the completion doorbell has not been initialized, and
calling bnxt_disable_int() will crash.  Fix it by checking that the
completion ring has been initialized before writing to the completion
ring doorbell.

Subject: net: qualcomm: qca: use new api ethtool_{get|set}_link_ksettings

The ethtool api {get|set}_settings is deprecated.
We move this driver to new api {get|set}_link_ksettings.

As I don't have the hardware, I'd be very pleased if
someone may test this patch.

Subject: net: mvpp2: fix DMA address calculation in mvpp2_txq_inc_put()

When TX descriptors are filled in, the buffer DMA address is split
between the tx_desc->buf_phys_addr field (high-order bits) and
tx_desc->packet_offset field (5 low-order bits).

However, when we re-calculate the DMA address from the TX descriptor in
mvpp2_txq_inc_put(), we do not take tx_desc->packet_offset into
account. This means that when the DMA address is not aligned on a 32
bytes boundary, we end up calling dma_unmap_single() with a DMA address
that was not the one returned by dma_map_single().

This inconsistency is detected by the kernel when DMA_API_DEBUG is
enabled. We fix this problem by properly calculating the DMA address in
mvpp2_txq_inc_put().

Subject: net: mvpp2: remove useless arguments in mvpp2_rx_{pkts,
 time}_coal_set

As noticed by Russell King, the last argument of
mvpp2_rx_{pkts,time}_coal_set() is useless, since the packet/time
coalescing value is already stored in the 'struct mvpp2_rx_queue *'
passed as argument to these functions. So passing the packet/time value
as an additional argument, and setting them again in the mvpp2_rx_queue
structure is useles.

This commit therefore gets rid of this additional argument, assuming the
caller has assigned the appropriate value to rxq->pkts_coal or
rxq->time_coal before calling the respective functions.

Subject: net: mvpp2: handle too large value handling in
 mvpp2_rx_pkts_coal_set()

Currently, mvpp2_rx_pkts_coal_set() does the following to avoid setting
a too large value for the RX coalescing by packet number:

  val = (pkts & MVPP2_OCCUPIED_THRESH_MASK);

This means that if you set a value that is slightly higher the the
maximum number of packets, you in fact get a very low value. It makes a
lot more sense to simply check if the value is too high, and if it's too
high, limit it to the maximum possible value.

Subject: net: mvpp2: handle too large value in mvpp2_rx_time_coal_set()

When configuring the MVPP2_ISR_RX_THRESHOLD_REG with the RX coalescing
time threshold, we do not check for the maximum allowed value supported
by the driver, which means we might overflow and use a bogus value. This
commit adds a check for this situation, and if a value higher than what
is supported by the hardware is provided, then we use the maximum value
supported by the hardware.

In order to achieve this in a way that avoids overflow and rounding
errors, we introduce two utility functions mvpp2_usec_to_cycles() and
cycles_to_usec(). Many thanks to Russell King for suggesting this
implementation.

unmap TX buffers, and free the corresponding SKBs. It gets the
references to the SKB to free and the DMA buffer to unmap from a per-CPU
txq_pcpu data structure.

However, the code currently increments the pointer to the next entry
before doing the DMA unmap and freeing the SKB. It does not cause any
visible problem because for a given SKB the TX completion is guaranteed
to take place on the CPU where the TX was started. However, it is much
more logical to increment the pointer to the next entry once the current
entry has been completely unmapped/released.

Subject: net: mvpp2: drop useless fields in mvpp2_bm_pool and related code

This commit drops dead code from the mvpp2 driver. The 'in_use' and
'in_use_thresh' fields of 'struct mvpp2_bm_pool' are
incremented/decremented/initialized in various places. But they are only
used in one place:

       if (is_recycle &&
           (atomic_read(&bm_pool->in_use) < bm_pool->in_use_thresh))
               return 0;

However 'is_recycle', passed as argument to mvpp2_rx_refill() is always
false. So in fact, this code is never reached, and the 'is_recycle'
argument is useless. So let's drop this code.

Subject: net: mvpp2: simplify mvpp2_bm_bufs_add()

The mvpp2_bm_bufs_add() currently creates a fake cookie by calling
mvpp2_bm_cookie_pool_set(), just to be able to call
mvpp2_pool_refill(). But all what mvpp2_pool_refill() does is extract
the pool ID from the cookie, and call mvpp2_bm_pool_put() with this ID.

Instead of doing this convoluted thing, just call mvpp2_bm_pool_put()
directly, since we have the BM pool ID.

Subject: net: mvpp2: simplify MVPP2_PRS_RI_* definitions
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Some of the MVPP2_PRS_RI_* definitions use the ~(value) syntax, which
doesn't compile nicely on 64-bit. Moreover, those definitions are in
fact unneeded, since they are always used in combination with a bit
mask that ensures only the appropriate bits are modified.

Therefore, such definitions should just be set to 0x0. In addition, as
suggested by Russell King, we change the _MASK definitions to also use
the BIT() macro so that it is clear they are related to the values
defined afterwards.

For example:

 #define MVPP2_PRS_RI_L2_CAST_MASK              0x600
 #define MVPP2_PRS_RI_L2_UCAST                  ~(BIT(9) | BIT(10))
 #define MVPP2_PRS_RI_L2_MCAST                  BIT(9)
 #define MVPP2_PRS_RI_L2_BCAST                  BIT(10)

becomes

 #define MVPP2_PRS_RI_L2_CAST_MASK              (BIT(9) | BIT(10))
 #define MVPP2_PRS_RI_L2_UCAST                  0x0
 #define MVPP2_PRS_RI_L2_MCAST                  BIT(9)
 #define MVPP2_PRS_RI_L2_BCAST                  BIT(10)

Because the values (MVPP2_PRS_RI_L2_UCAST, MVPP2_PRS_RI_L2_MCAST and
MVPP2_PRS_RI_L2_BCAST) are always applied with
MVPP2_PRS_RI_L2_CAST_MASK, and therefore there is no need for
MVPP2_PRS_RI_L2_UCAST to be defined as ~(BIT(9) | BIT(10)).

It fixes the following warnings when building the driver on a 64-bit
platform (which is not possible as of this commit, but will be enabled
in a follow-up commit):

Subject: net: mvpp2: switch to build_skb() in the RX path

This commit adapts the mvpp2 RX path to use the build_skb() method. Not
only build_skb() is now the recommended mechanism, but it also
simplifies the addition of support for the PPv2.2 variant.

Indeed, without build_skb(), we have to keep track for each RX
descriptor of the physical address of the packet buffer, and the virtual
address of the SKB. However, in PPv2.2 running on 64 bits platform,
there is not enough space in the descriptor to store the virtual address
of the SKB. So having to take care only of the address of the packet
buffer, and building the SKB upon reception helps in supporting PPv2.2.

The implementation is fairly straightforward:

 - mvpp2_skb_alloc() is renamed to mvpp2_buf_alloc() and no longer
   allocates a SKB. Instead, it allocates a buffer using the new
   mvpp2_frag_alloc() function, with enough space for the data and SKB.

 - The initialization of the RX buffers in mvpp2_bm_bufs_add() as well
   as the refill of the RX buffers in mvpp2_rx_refill() is adjusted
   accordingly.

 - Finally, the mvpp2_rx() is modified to use build_skb().

Subject: net: mvpp2: enable building on 64-bit platforms

The mvpp2 is going to be extended to support the Marvell Armada 7K/8K
platform, which is ARM64. As a preparation to this work, this commit
enables building the mvpp2 driver on ARM64, by:

 - Adjusting the Kconfig dependency

 - Fixing the types used in the driver so that they are 32/64-bits
   compliant. We use dma_addr_t for DMA addresses, and unsigned long
   for virtual addresses.

It is worth mentioning that after this commit, the driver is for now
still only used on 32-bits platforms, and will only work on 32-bits
platforms.

Subject: net: emac: add support for device-tree based PHY discovery and setup

This patch adds glue-code that allows the EMAC driver to interface
with the existing dt-supported PHYs in drivers/net/phy.

Because currently, the emac driver maintains a small library of
supported phys for in a private phy.c file located in the drivers
directory.

The support is limited to mostly single ethernet transceiver like the:
CIS8201, BCM5248, ET1011C, Marvell 88E1111 and 88E1112, AR8035.

However, routers like the Netgear WNDR4700 and Cisco Meraki MX60(W)
have a 5-port switch (AR8327N) attached to the EMAC. The switch chip
is supported by the qca8k mdio driver, which uses the generic phy
library. Another reason is that PHYLIB also supports the BCM54610,
which was used for the Western Digital My Book Live.

This will now also make EMAC select PHYLIB.

Declare bin_attribute structures as const as they are only passed as an
arguments to the functions device_remove_bin_file and
device_create_bin_file. These function arguments are of type const, so
bin_attribute structures having this property can be made const too.

Subject: lib/show_mem.c: teach show_mem to work with the given nodemask

show_mem() allows to filter out node specific data which is irrelevant
to the allocation request via SHOW_MEM_FILTER_NODES.  The filtering is
done in skip_free_areas_node which skips all nodes which are not in the
mems_allowed of the current process.  This works most of the time as
expected because the nodemask shouldn't be outside of the allocating
task but there are some exceptions.  E.g.  memory hotplug might want to
request allocations from outside of the allowed nodes (see
new_node_page).

Get rid of this hardcoded behavior and push the allocation mask down the
show_mem path and use it instead of cpuset_current_mems_allowed.  NULL
nodemask is interpreted as cpuset_current_mems_allowed.

Subject: net/mlx5e: Register/unregister vport representors on interface
 attach/detach

Currently vport representors are added only on driver load and removed on
driver unload.  Apparently we forgot to handle them when we added the
seamless reset flow feature.  This caused to leave the representors
netdevs alive and active with open HW resources on pci shutdown and on
error reset flows.

To overcome this we move their handling to interface attach/detach, so
they would be cleaned up on shutdown and recreated on reset flows.

Subject: net/mlx5e: Fix broken CQE compression initialization

Some of RQ type parameters are derived from CQE compression state flag,
CQE compression flag was initialized only after RQ type parameters
setup. This leads to load RQ with stride size smaller than what we
want for when CQE compression is on.

This bug introduces no functional damage, it only makes CQE compression
occur less often, since in ConnectX4-LX CQE compression is performed
only on packets smaller than stride size.

Fix this by marking default status of CQE compression in PFLAG prior to
calling mlx5e_set_rq_priv_params(), as it inits some fields based on it.

Tested:
 load driver on systems where rx CQE compress will be on (MH)
 pktgen with  64 < pkt size < 256 and netperf TCP_STREAM (IPv4/IPv6)
 verify `ethtool -S ethxx | grep compress` are advancing more often
 (rapidly)

Subject: net/mlx5e: Update MPWQE stride size when modifying CQE compress state

When the admin enables/disables cqe compression, updating
mpwqe stride size is required:
    CQE compress ON  ==> stride size = 256B
    CQE compress OFF ==> stride size = 64B

This is already done on driver load via mlx5e_set_rq_type_params, all we
need is just to call it on arbitrary admin changes of cqe compression
state via priv flags or when changing timestamping state
(as it is mutually exclusive with cqe compression).

This bug introduces no functional damage, it only makes cqe compression
occur less often, since in ConnectX4-LX CQE compression is performed
only on packets smaller than stride size.

Tested:
 ethtool --set-priv-flags ethxx rx_cqe_compress on
 pktgen with  64 < pkt size < 256 and netperf TCP_STREAM (IPv4/IPv6)
 verify `ethtool -S ethxx | grep compress` are advancing more often

Subject: net/mlx5e: Fix wrong CQE decompression

In cqe compression with striding RQ, the decompression of the CQE field
wqe_counter was done with a wrong wraparound value.
This caused handling cqes with a wrong pointer to wqe (rx descriptor)
and creating SKBs with wrong data, pointing to wrong (and already consumed)
strides/pages.

The meaning of the CQE field wqe_counter in striding RQ holds the
stride index instead of the WQE index. Hence, when decompressing
a CQE, wqe_counter should have wrapped-around the number of strides
in a single multi-packet WQE.

We dropped this wrap-around mask at all in CQE decompression of striding
RQ. It is not needed as in such cases the CQE compression session would
break because of different value of wqe_id field, starting a new
compression session.

Tested:
 ethtool -K ethxx lro off/on
 ethtool --set-priv-flags ethxx rx_cqe_compress on
 super_netperf 16 {ipv4,ipv6} -t TCP_STREAM -m 50 -D
 verified no csum errors and no page refcount issues.

Subject: net/mlx4_core: Fix VF overwrite of module param which disables DMFS
 on new probed PFs

In the VF driver, module parameter mlx4_log_num_mgm_entry_size was
mistakenly overwritten -- and in a manner which overrode the
device-managed flow steering option encoded in the parameter.

log_num_mgm_entry_size is a global module parameter which
affects all ConnectX-3 PFs installed on that host.
If a VF changes log_num_mgm_entry_size, this will affect all PFs
which are probed subsequent to the change (by disabling DMFS for
those PFs).

Subject: net/mlx4_core: Use cq quota in SRIOV when creating completion EQs

When creating EQs to handle CQ completion events for the PF
or for VFs, we create enough EQE entries to handle completions
for the max number of CQs that can use that EQ.

When SRIOV is activated, the max number of CQs a VF (or the PF) can
obtain is its CQ quota (determined by the Hypervisor resource tracker).
Therefore, when creating an EQ, the number of EQE entries that the VF
should request for that EQ is the CQ quota value (and not the total
number of CQs available in the FW).

Under SRIOV, the PF, also must use its CQ quota, because
the resource tracker also controls how many CQs the PF can obtain.

Using the FW total CQs instead of the CQ quota when creating EQs resulted
wasting MTT entries, due to allocating more EQEs than were needed.

Subject: net: stmmac: unify registers dumps methods

The stmmac driver have two methods for registers dumps: via ethtool and
at init (if NETIF_MSG_HW is enabled).

It is better to keep only one method, ethtool, since the other was ugly.

This patch convert all dump_regs() function from "printing regs" to
"fill the reg_space used by ethtool".

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

With gcc-4.1.2 and -Os:

    drivers/net/ethernet/apm/xgene/xgene_enet_main.c: In function ‘xgene_enet_start_xmit’:
    drivers/net/ethernet/apm/xgene/xgene_enet_main.c:297: warning: ‘mss_index’ may be used uninitialized in this function

Using a separate variable to track success may confuse the compiler.
Preinitialize mss_index with -EBUSY and check for negative error values
instead to kill the warning.

Subject: net/mlx4_en: fix overflow in mlx4_en_init_timestamp()

The cited commit makes a great job of finding optimal shift/multiplier
values assuming a 10 seconds wrap around, but forgot to change the
overflow_period computation.

It overflows in cyclecounter_cyc2ns(), and the final result is 804 ms,
which is silly.

Lets simply use 5 seconds, no need to recompute this, given how it is
supposed to work.

Later, we will use a timer instead of a work queue, since the new RX
allocation schem will no longer need mlx4_en_recover_from_oom() and the
service_task firing every 250 ms.

Subject: qed: Fix race with multiple VFs

A PF syncronizes all IOV activity relating to its VFs
by using a single workqueue handling the work.
The workqueue would reach a bitmask of pending VF events
and act upon each in turn.

Problem is that the indication of a VF message [which sets
the 'vf event' bit for that VF] arrives and is set in
the slowpath attention context, which isn't syncronized with
the processing of the events.
When multiple VFs are present, it's possible that PF would
lose the indication of one of the VF's pending evens, leading
that VF to later timeout.

Instead of adding locks/barriers, simply move from a bitmask
into a per-VF indication inside that VF entry in the PF database.

Subject: qed: Don't use attention PTT for configuring BW

Commit 653d2ffd6405 ("qed*: Fix link indication race") introduced another
race - one of the inner functions called from the link-change flow is
explicitly using the slowpath context dedicated PTT instead of gaining
that PTT from the caller. Since this flow can now be called from
a different context as well, we're in risk of the PTT breaking.

Subject: scripts/spelling.txt: add "comsume(r)" pattern and fix typo instances

Fix typos and add the following to the scripts/spelling.txt:

  comsume||consume
  comsumer||consumer
  comsuming||consuming

I see some variable names with this pattern, but this commit is only
touching comment blocks to avoid unexpected impact.

Fix typos and add the following to the scripts/spelling.txt:

The "applyes" in drivers/video/fbdev/aty/radeon_monitor.c is a different
pattern but it was fixed in this commit.  The "This functions" in the
same line was fixed as well.

Subject: lib/vsprintf.c: remove %Z support

Now that %z is standartised in C99 there is no reason to support %Z.
Unlike %L it doesn't even make format strings smaller.

Use BUILD_BUG_ON in a couple ATM drivers.

In case anyone didn't notice lib/vsprintf.o is about half of SLUB which
is in my opinion is quite an achievement.  Hopefully this patch inspires
someone else to trim vsprintf.c more.

Subject: mlxsw: spectrum_router: Avoid potential packets loss

When the structure of the LPM tree changes (f.e., due to the addition of
a new prefix), we unbind the old tree and then bind the new one. This
may result in temporary packet loss.

Instead, overwrite the old binding with the new one.

Subject: drivers: net: xgene: Fix crash on DT systems

On DT systems the driver require a clock, but the probe just print a
warning and continue, leading to a crash when resetting the device.
To fix this crash and properly handle probe deferals only ignore the
missing clock if DT isn't used or if the clock doesn't exist.

Subject: amd-xgbe: Stop the PHY before releasing interrupts

Some configurations require the use of the hardware's MDIO support to
communicate with external PHYs. The MDIO commands indicate completion
through the device interrupt. When bringing down the device the interrupts
were released before stopping the external PHY, resulting in MDIO command
timeouts. Move the stopping of the PHY to before the releasing of the
interrupts.

The MDIO register mode is set when the device is probed. But when the
device is brought down and then back up, the MDIO register mode has been
reset.  Be sure to reset the mode during device startup and only change
the mode of the address specified.

Subject: drivers: net: ethernet: remove incorrect __exit markups

Even if bus is not hot-pluggable, devices can be unbound from the
driver via sysfs, so we should not be using __exit annotations on
remove() methods. The only exception is drivers registered with
platform_driver_probe() which specifically disables sysfs bind/unbind
attributes.

Subject: ixgbe: update the rss key on h/w, when ethtool ask for it

Currently ixgbe_set_rxfh() updates the rss_key copy in the driver
memory, but does not push the new value into the h/w. This commit
add a new helper for the latter operation and call it in
ixgbe_set_rxfh(), so that the h/w rss key value can be really
updated via ethtool.

Subject: ixgbe: Limit use of 2K buffers on architectures with 256B or larger
 cache lines

On architectures that have a cache line size larger than 64 Bytes we start
running into issues where the amount of headroom for the frame starts
shrinking.

The size of skb_shared_info on a system with a 64B L1 cache line size is
320.  This increases to 384 with a 128B cache line, and 512 with a 256B
cache line.

In addition the NET_SKB_PAD value increases as well consistent with the
cache line size.  As a result when we get to a 256B cache line as seen on
the s390 we end up 768 bytes used by padding and shared info leaving us
with only 1280 bytes to use for data storage.  On architectures such as
this we should default to using 3K Rx buffers out of a 8K page instead of
trying to do 1.5K buffers out of a 4K page.

To take all of this into account I have added one small check so that we
compare the max_frame to the amount of actual data we can store.  This was
already occurring for igb, but I had overlooked it for ixgbe as it doesn't
have strict limits for 82599 once we enable jumbo frames.  By adding this
check we will automatically enable 3K Rx buffers as soon as the maximum
frame size we can handle drops below the standard Ethernet MTU.

I also went through and fixed one small typo that I found where I had left
an IGB in a variable name due to a copy/paste error.

Subject: net: ethernet: bgmac: init sequence bug

Fix a bug in the 'bgmac' driver init sequence that blind writes for init
sequence where it should preserve most bits other than the ones it is
deliberately manipulating.

The code now checks to see if the adapter needs to be brought out of
reset (where as before it was doing an IDM write to bring it out of
reset regardless of whether it was in reset or not).  Also, removed
unnecessary usleeps (as there is already a read present to flush the
IDM writes).

Subject: nfp: don't tell FW about the reserved buffer space

Since commit c0f031bc8866 ("nfp_net: use alloc_frag() and build_skb()")
we are allocating buffers which have to hold both the data and skb to
be created in place by build_skb().

FW should only be told about the buffer space it can DMA to, that
is without the build_skb() headroom and tailroom.  Note: firmware
applications should validate the buffers against both MTU and
free list buffer size so oversized packets would not pass through
the NIC anyway.

Subject: sfc: avoid max() in array size

It confuses sparse, which thinks the size isn't constant.  Let's achieve
 the same thing with a BUILD_BUG_ON, since we know which one should be
 bigger and don't expect them ever to change.

Subject: sfc: fix IPID endianness in TSOv2

The value we read from the header is in network byte order, whereas
 EFX_POPULATE_QWORD_* takes values in host byte order (which it then
 converts to little-endian, as MCDI is little-endian).
