All the registers and the functionalities used in the callback
dwmac5_flex_pps_config() are common between dwmac 4.10a [1] and
5.00a [2].
Reuse the same callback for dwmac 4.10a too.
Tested on STM32MP15x, based on dwmac 4.10a.

This reverts commit 0ad646c81b2182f7fa67ec0c8c825e0ee165696d.
As noticed by Jakub, this is no longer needed after
commit 11fc7d5a0a2d ("tun: fix memory leak in error path")
This no longer exports dev_get_valid_name() for the exclusive
use of tun driver.

Individual dumpit ops (start, dumpit, done) are locked by genl_lock
if !family->parallel_ops. However, multiple
genl_family_rcv_msg_dumpit() calls may in in flight in parallel.
Each has a separate struct genl_dumpit_info allocated
but they share the same family->attrbuf. Fix this by allocating separate
memory for attrs for dumpit ops, for non-parallel_ops (for parallel_ops
it is done already).

The hardware supports up to 8 TX BD for non-tso skb and up to
63 TX BD for TSO skb. Currently, the hns3 driver supports RX skb
with fraglist when HW GRO is enabled, when the stack forwards a
RX skb with fraglist, the stack need to linearize the skb before
sending to other interface without TX fraglist support.
This patch adds support for TX fraglist. The performance increases
from 1 GByte to 1.5 GByte for one iperf TCP stream during
forwarding test after this patch. BTW, the minimum BD number of
ring should be updated to 72 for supporting TX fraglist.
This patch also changes the error handling of some function that
called by hns3_fill_desc, which returns BD num when there is no
error, change some macro to more meaningful name.

This patch adds support of configuring VF MAC from the host
for the HNS3 driver.
BTW, the parameter init in the hns3_init_mac_addr is
unnecessary now, since the MAC address will not read from
NCL_CONFIG when doing reset, so it should be removed,
otherwise it will affect VF's MAC address initialization.

This patch adds supports for setting VF trust by host. If specified
VF is trusted, then it can enable promisc(include allmulti mode).
If a trusted VF enabled promisc, and being untrusted, host will
disable promisc mode for this VF.
For VF will update its promisc mode from set_rx_mode now, so it's
unnecessary to set broadcst promisc mode when initialization or
reset.

This patch adds support for spoof check configuration for VFs.
When it is enabled, "spoof checking" is done for both mac address
and VLAN. For each VF, the HW ensures that the source MAC address
(or VLAN) of every outgoing packet exists in the MAC-list (or
VLAN-list) configured for RX filtering for that VF. If not,
the packet is dropped.

syzbot reported a warning [1] that triggered after recent Jiri patch.
This exposes a bug that we hit already in the past (see commit
ff244c6b29b1 ("tun: handle register_netdevice() failures properly")
for details)
tun uses priv->destructor without an ndo_init() method.
register_netdevice() can return an error, but will
not call priv->destructor() in some cases. Jiri recent
patch added one more.
A long term fix would be to transfer the initialization
of what we destroy in ->destructor() in the ndo_init()
This looks a bit risky given the complexity of tun driver.
A simpler fix is to detect after the failed register_netdevice()
if the tun_free_netdev() function was called already.

SPI is one of the interfaces used to access devices which have a POSIX
clock driver (real time clocks, 1588 timers etc). The fact that the SPI
bus is slow is not what the main problem is, but rather the fact that
drivers don't take a constant amount of time in transferring data over
SPI. When there is a high delay in the readout of time, there will be
uncertainty in the value that has been read out of the peripheral.
When that delay is constant, the uncertainty can at least be
approximated with a certain accuracy which is fine more often than not.
Timing jitter occurs all over in the kernel code, and is mainly caused
by having to let go of the CPU for various reasons such as preemption,
servicing interrupts, going to sleep, etc. Another major reason is CPU
dynamic frequency scaling.
It turns out that the problem of retrieving time from a SPI peripheral
with high accuracy can be solved by the use of "PTP system
timestamping" - a mechanism to correlate the time when the device has
snapshotted its internal time counter with the Linux system time at that
same moment. This is sufficient for having a precise time measurement -
it is not necessary for the whole SPI transfer to be transmitted "as
fast as possible", or "as low-jitter as possible". The system has to be
low-jitter for a very short amount of time to be effective.
This patch introduces a PTP system timestamping mechanism in struct
spi_transfer. This is to be used by SPI device drivers when they need to
know the exact time at which the underlying device's time was
snapshotted. More often than not, SPI peripherals have a very exact
timing for when their SPI-to-interconnect bridge issues a transaction
for snapshotting and reading the time register, and that will be
dependent on when the SPI-to-interconnect bridge figures out that this
is what it should do, aka as soon as it sees byte N of the SPI transfer.
Since spi_device drivers are the ones who'd know best how the peripheral
behaves in this regard, expose a mechanism in spi_transfer which allows
them to specify which word (or word range) from the transfer should be
timestamped.
Add a default implementation of the PTP system timestamping in the SPI
core. This is not going to be satisfactory performance-wise, but should
at least increase the likelihood that SPI device drivers will use PTP
system timestamping in the future.
There are 3 entry points from the core towards the SPI controller
drivers:
- transfer_one: The driver is passed individual spi_transfers to
execute. This is the easiest to timestamp.
- transfer_one_message: The core passes the driver an entire spi_message
(a potential batch of spi_transfers). The core puts the same pre and
post timestamp to all transfers within a message. This is not ideal,
but nothing better can be done by default anyway, since the core has
no insight into how the driver batches the transfers.
- transfer: Like transfer_one_message, but for unqueued drivers (i.e.
the driver implements its own queue scheduling).

Throughout the driver there are several places where we wait
indefinitely for DPIO portal commands to be executed, while
the portal returns a busy response code.
Even though in theory we are guaranteed the portals become
available eventually, in practice the QBMan hardware module
may become unresponsive in various corner cases.
Make sure we can never get stuck in an infinite while loop
by adding a retry counter for all portal commands.

This commit adds the feature to specify the destination address range with CIDR.
-d : ($DEST_IP) destination IP. CIDR (e.g. 198.18.0.0/15) is also allowed

This commit adds CIDR parsing and IP validate helper function to parse
single IP or range of IP with CIDR. (e.g. 198.18.0.0/15)
Validating the address should be preceded prior to the parsing.
Helpers will be used in prior to set target address in samples/pktgen.

Currently, proc_cmd is used to dispatch command to 'pg_ctrl', 'pg_thread',
'pg_set'. proc_cmd is designed to check command result with grep the
"Result:", but this might fail since this string is only shown in
'pg_thread' and 'pg_set'.
This commit fixes this logic by grep-ing the "Result:" string only when
the command is not for 'pg_ctrl'.
For clarity of an execution flow, 'errexit' flag has been set.
To cleanup pktgen on exit, trap has been added for EXIT signal.

This commit changes variable names that can cause confusion.
For example, variable DST_MIN is quite confusing since the
keyword 'udp_dst_min' and keyword 'dst_min' is used with pg_ctrl.
On the following commit, 'dst_min' will be used to set destination IP,
and the existing variable name DST_MIN should be changed.
Variable names are matched to the exact keyword used with pg_ctrl.

If VLAN Hash Filtering is not available we can fallback to perfect
filtering instead. Let's implement this in XGMAC and GMAC cores and let
the user use this filter.
VLAN VID=0 always passes filter so we check if more than 2 VLANs are
created and return proper error code if so because perfect filtering
only supports 1 VID at a time.

Add validation for FW version in order to prevent driver initialization
in case FW version is older than expected. FW version validation is
necessary, because use of a new field 'num_of_modules' in MGPIR register
is not backward compatible. FW 'minor' and 'subminor' versions are
expected to be greater than or equal to 2000 and 1886, respectively.
