A queue can't belong to multiple traffic classes. So, reject
any such configuration that results in overlapped queues for a
traffic class.

T6 can support 2 egress traffic management channels per port to
double the total number of traffic classes that can be configured.
In this configuration, if the class belongs to the other channel,
then all the queues must be bound again explicitly to the new class,
for the rate limit parameters on the other channel to take effect.
So, always explicitly bind all queues to the port rate limit traffic
class, regardless of the traffic management channel that it belongs
to. Also, only bind queues to port rate limit traffic class, if all
the queues don't already belong to an existing different traffic
class.

DSN read can fail, for example on a kdump kernel without PCIe extended
config space support. If DSN read fails, don't set the
BNXT_FLAG_DSN_VALID flag and continue loading. Check the flag
to see if the stored DSN is valid before using it. Only VF reps
creation should fail without valid DSN.

We would not be transmitting using the correct SYSTEMPORT transmit queue
during ndo_select_queue() which looks up the internal TX ring map
because while establishing the mapping we would be off by 4, so for
instance, when we populate switch port mappings we would be doing:
switch port 0, queue 0 -> ring index #0
switch port 0, queue 1 -> ring index #1
...
switch port 0, queue 3 -> ring index #3
switch port 1, queue 0 -> ring index #8 (4 + 4 * 1)
...
instead of using ring index #4. This would cause our ndo_select_queue()
to use the fallback queue mechanism which would pick up an incorrect
ring for that switch port. Fix this by using the correct switch queue
number instead of SYSTEMPORT queue number.

port for 2Gb/sec, the default is 1Gb/sec. This is needed given the

When there is not enough memory and napi_alloc_skb() return NULL,
the HNS driver will print error message, and than try again, if
the memory is not enough for a while, huge error message and the
retry operation will cause soft lockup.
When napi_alloc_skb() return NULL because of no memory, we can
get a warn_alloc() call trace, so this patch deletes the error
message. We already use polling mode to handle irq, but the
retry operation will render the polling weight inactive, this
patch just return budget when the rx is not completed to avoid
dead loop.

mlxsw configures Spectrum in such a way that BUM traffic is passed not
through its nominal traffic class TC, but through its MC counterpart TC+8.
However, when collecting statistics, Qdiscs only look at the nominal TC and
ignore the MC TC.
Add two helpers to compute the value for logical TC from the constituents,
one for backlog, the other for tail drops. Use them throughout instead of
going through the xstats pointer directly.
Counters for TX bytes and packets are deduced from packet priority
counters, and therefore already include BUM traffic. wred_drop counter is
irrelevant on MC TCs, because RED is not enabled on them.

Per-port counter cache used by Qdiscs is updated periodically, unless the
port is down. The fact that the cache is not updated for down ports is no
problem for most counters, which are relative in nature. However, backlog
is absolute in nature, and if there is a non-zero value in the cache around
the time that the port goes down, that value just stays there. This value
then leaks to offloaded Qdiscs that report non-zero backlog even if
there (obviously) is no traffic.
The HW does not keep backlog of a downed port, so do likewise: as the port
goes down, wipe the backlog value from xstats.

The driver needs to prepend a Tx header to each packet it is
transmitting. The header includes information such as the egress port
and traffic class.
The addition of the header requires the driver to modify the SKB's
header and therefore it must not be shared. Otherwise, we risk hitting
various race conditions.
For example, when a packet is flooded (cloned) by the bridge driver to
two switch ports swp1 and swp2:
t0 - mlxsw_sp_port_xmit() is called for swp1. Tx header is prepended with
swp1's port number
t1 - mlxsw_sp_port_xmit() is called for swp2. Tx header is prepended with
swp2's port number, overwriting swp1's port number
t2 - The device processes data buffer from t0. Packet is transmitted via
swp2
t3 - The device processes data buffer from t1. Packet is transmitted via
swp2
Usually, the device is fast enough and transmits the packet before its
Tx header is overwritten, but this is not the case in emulated
environments.
Fix this by making sure the SKB's header is writable by calling
skb_cow_head(). Since the function ensures we have headroom to push the
Tx header, the check further in the function can be removed.
v2:
* Use skb_cow_head() instead of skb_unshare() as suggested by Jakub
* Remove unnecessary check regarding headroom

t3 - The device processes data buffer from t1. Packet is transmitted via
swp2
Usually, the device is fast enough and transmits the packet before its
Tx header is overwritten, but this is not the case in emulated
environments.
Fix this by making sure the SKB's header is writable by calling
skb_cow_head(). Since the function ensures we have headroom to push the
Tx header, the check further in the function can be removed.
v2:
* Use skb_cow_head() instead of skb_unshare() as suggested by Jakub
* Remove unnecessary check regarding headroom

In commit a72afb6879bb ("mlxsw: Enforce firmware version for
Spectrum-2") I added a required firmware version for Spectrum-2, but
missed the fact that mlxsw_sp2_init() is used by both Spectrum-2 and
Spectrum-3. This means that the same firmware version will be used for
both, which is wrong.
Fix this by creating a new init() callback for Spectrum-3.

lan78xx_tx_bh() makes sure to not exceed MAX_SINGLE_PACKET_SIZE
bytes in the aggregated packets it builds, but does
nothing to prevent large GSO packets being submitted.
Pierre-Francois reported various hangs when/if TSO is enabled.
For localy generated packets, we can use netif_set_gso_max_size()
to limit the size of TSO packets.
Note that forwarded packets could still hit the issue,
so a complete fix might require implementing .ndo_features_check
for this driver, forcing a software segmentation if the size
of the TSO packet exceeds MAX_SINGLE_PACKET_SIZE.

There is a bug in ptp_clock_unregister(), where ptp_cleanup_pin_groups()
first frees ptp->pin_{,dev_}attr, but then posix_clock_unregister() needs
them to destroy a related sysfs device.
These functions can not be just swapped, as posix_clock_unregister() frees
ptp which is needed in the ptp_cleanup_pin_groups(). Fix this by calling
ptp_cleanup_pin_groups() in ptp_clock_release(), right before ptp is freed.

The driver was doing a synchronous uninterruptible bulk-transfer without
using a timeout. This could lead to the driver hanging on probe due to a
malfunctioning (or malicious) device until the device is physically
disconnected. While sleeping in probe the driver prevents other devices
connected to the same hub from being added to (or removed from) the bus.
An arbitrary limit of five seconds should be more than enough.

Intel Wired LAN Driver Updates 2020-01-09
This series contains fixes to e1000e, igb, ixgbe, ixgbevf, i40e and iavf
drivers.
Brett fixes the validation of the virtchnl queue select bitmaps by
comparing the bitmaps against BIT(I40E_MAX_VF_QUEUES).
Radoslaw removes the limitation of only 10 filter entries for a VF and
allows use of all free RAR entries for the forwarding database, if
needed.
Cambda Zhu fixes the calculation of queue when restoring flow director
filters after resetting the adapter for ixgbe.
Manfred Rudigier fixes the SGMIISFP module discovery for 100FX/LX
modules for igb.
Stefan Assmann fixes iavf where during a VF reset event, MAC filters
were not altered, which could lead to a stale filter when an
administratively set MAC address is forced by the PF.
Adam adds the missing code to set the PHY access flag on X722 devices,
which supports accessing PHY registers with the admin queue command.
Revert a previous commit for e1000e to use "delayed work" which was
causing connections to reset unexpectedly and possible driver crashes.

Currently MAC filters are not altered during a VF reset event. This may
lead to a stale filter when an administratively set MAC is forced by the
PF.
For an administratively set MAC the PF driver deletes the VFs filters,
overwrites the VFs MAC address and triggers a VF reset. However
the VF driver itself is not aware of the filter removal, which is what
the VF reset is for.
The VF reset queues all filters present in the VF driver to be re-added
to the PF filter list (including the filter for the now stale VF MAC
address) and triggers a VIRTCHNL_OP_GET_VF_RESOURCES event, which
provides the new MAC address to the VF.
When this happens i40e will complain and reject the stale MAC filter,
at least in the untrusted VF case.
i40e 0000:08:00.0: Setting MAC 3c:fa:fa:fa:fa:01 on VF 0
iavf 0000:08:02.0: Reset warning received from the PF
iavf 0000:08:02.0: Scheduling reset task
i40e 0000:08:00.0: Bring down and up the VF interface to make this change effective.
i40e 0000:08:00.0: VF attempting to override administratively set MAC address, bring down and up the VF interface to resume normal operation
i40e 0000:08:00.0: VF 0 failed opcode 10, retval: -1
iavf 0000:08:02.0: Failed to add MAC filter, error IAVF_ERR_NVM
To avoid re-adding the stale MAC filter it needs to be removed from the
VF driver's filter list before queuing the existing filters. Then during
the VIRTCHNL_OP_GET_VF_RESOURCES event the correct filter needs to be
added again, at which point the MAC address has been updated.
As a bonus this change makes bringing the VF down and up again
superfluous for the administratively set MAC case.

Currently in i40e_vc_disable_queues_msg() we are incorrectly
validating the virtchnl queue select bitmaps. The
virtchnl_queue_select rx_queues and tx_queue bitmap is being
compared against ICE_MAX_VF_QUEUES, but the problem is that
these bitmaps can have a value greater than I40E_MAX_VF_QUEUES.
Fix this by comparing the bitmaps against BIT(I40E_MAX_VF_QUEUES).
Also, add the function i40e_vc_validate_vqs_bitmaps() that checks to see
if both virtchnl_queue_select bitmaps are empty along with checking that
the bitmaps only have valid bits set. This function can then be used in
both the queue enable and disable flows.
