net/smc: Enable module load on netlink usage
Previously, the smc and smc_diag modules were automatically loaded as
dependencies of the ism module whenever an ISM device was present.
With the pending rework of the ISM API, the smc module will no longer
automatically be loaded in presence of an ISM device. Usage of an AF_SMC
socket will still trigger loading of the smc modules, but usage of a
netlink socket will not.
This is addressed by setting the correct module aliases.

Some group of switches have some register address and bit fields common and
others are different. So, this patch aims to have common phylink implementation
which configures the register based on the chip id.
Changes in v2
- combined the modification of duplex, tx_pause and rx_pause into single

- Squash the reading rgmii value from dt to patch which apply the rgmii value
- Created the new function ksz_port_set_xmii_speed

tls: rx: do not use the standard strparser
TLS is a relatively poor fit for strparser. We pause the input
every time a message is received, wait for a read which will
decrypt the message, start the parser, repeat. strparser is
built to delineate the messages, wrap them in individual skbs
and let them float off into the stack or a different socket.
TLS wants the data pages and nothing else. There's no need
for TLS to keep cloning (and occasionally skb_unclone()'ing)
the TCP rx queue.
This patch uses a pre-allocated skb and attaches the skbs
from the TCP rx queue to it as frags. TLS is careful never
to modify the input skb without CoW'ing / detaching it first.
Since we call TCP rx queue cleanup directly we also get back
the benefit of skb deferred free.
Overall this results in a 6% gain in my benchmarks.

1) "devlink dev info" is exposed for line card (patches 6-9)
2) "devlink dev flash" is implemented for line card gearbox
flashing (patch 10)
For every line card, "a nested" auxiliary device is created which

The relationship between line card and its auxiliary dev devlink
is carried over extra line card netlink attribute (patches 3 and 5).
The first patch removes devlink_mutex from devlink_register/unregister()
which eliminates possible deadlock during devlink reload command. The
second patchset follows up with putting net pointer check into new

There is a reference taken when working with devlink using
devlink_try_get(). But there is no guarantee that devlink pointer
picked during xarray iteration is not freed before devlink_try_get()
is called.
Make sure that devlink_try_get() works with valid pointer.
Achieve it by:
1) Splitting devlink_put() so the completion is sent only
after grace period. Completion unblocks the devlink_unregister()
routine, which is followed-up by devlink_free()
2) During devlinks xa_array iteration, get devlink pointer from xa_array
holding RCU read lock and taking reference using devlink_try_get()
before unlock.

Octeontx2 minor tc fixes
This patch set fixes two problems found in tc code

Patch 1: CN10K has different register format compared to

Patch 2: Check flow mask also before installing a src/dst

====================
Add MTU change with stmmac interface running
This series is to permit MTU change while the interface is running.
Major rework are needed to permit to allocate a new dma conf based on
the new MTU before applying it. This is to make sure there is enough
space to allocate all the DMA queue before releasing the stmmac driver.
This was tested with a simple way to stress the network while the
interface is running.
2 ssh connection to the device:
- One generating simple traffic with while true; do free; done
- The other making the mtu change with a delay of 1 second
The connection is correctly stopped and recovered after the MTU is changed.
The first 2 patch of this series are minor fixup that fix problems
presented while testing this. One fix a problem when we renable a queue
while we are generating a new dma conf. The other is a corner case that
was notice while stressing the driver and turning down the interface while
there was some traffic.
(this is a follow-up of a simpler patch that wanted to add the same
feature. It was suggested to first try to check if it was possible to
apply the new configuration. Posting as RFC as it does major rework for
the new concept of DMA conf)

net: macb: Update tsu clk usage in runtime suspend/resume for Versal
On Versal TSU clock cannot be disabled irrespective of whether PTP is
used. Hence introduce a new Versal config structure with a "need tsu"
caps flag and check the same in runtime_suspend/resume before cutting
off clocks.
More information on this for future reference:
This is an IP limitation on versions 1p11 and 1p12 when Qbv is enabled
(See designcfg1, bit 3). However it is better to rely on an SoC specific
check rather than the IP version because tsu clk property itself may not
represent actual HW tsu clock on some chip designs.
