1) Remove kernel log prints on FW events regarding FW pages management
    and replace that with debugfs entries to track FW pages management commands
    failures and general stats, we do that for all FW commands in general since
    it's the same effort to do so under the already existing debugfs entry for
    FW commands.
 
 2) Add support for ConnectX-7 Software managed steering, in other words STEv2
    which shares a lot in common with STE V1, the difference is in specific
    offsets in the devices, the logic is almost the same, thus we implement
    STEv1 and STEv2 in the same file.

Mat Martineau says:

====================
mptcp: selftests: Refactor join tests

The mptcp_join.sh selftest is the largest and most complex self test for
MPTCP, and it is frequently used by MPTCP developers to reproduce bugs
and verify fixes. As it grew in size and execution time, it became more
cumbersome to use.

These changes do some much-needed cleanup, and add developer-friendly
features to make it easier to see failures and run a subset of the tests
when verifying fixes.

d8d0830205 selftests: mptcp: join: make it shellcheck compliant
This fixes a few issues reported by ShellCheck:

- SC2068: Double quote array expansions to avoid re-splitting elements.
- SC2206: Quote to prevent word splitting/globbing, or split robustly
          with mapfile or read -a.
- SC2166: Prefer [ p ] && [ q ] as [ p -a q ] is not well defined.
- SC2155: Declare and assign separately to avoid masking return values.
- SC2162: read without -r will mangle backslashes.
- SC2219: Instead of 'let expr', prefer (( expr )) .
- SC2181: Check exit code directly with e.g. 'if mycmd;', not indirectly
          with $?.
- SC2236: Use -n instead of ! -z.
- SC2004: $/${} is unnecessary on arithmetic variables.
- SC2012: Use find instead of ls to better handle non-alphanumeric
          filenames.
- SC2002: Useless cat. Consider 'cmd < file | ..' or 'cmd file | ..'
          instead.

SC2086 (Double quotes to prevent globbing and word splitting) is ignored
because it is controlled for the moment and there are too many to
change.

While at it, also fixed the alignment in one comment.

4bfadd7120 selftests: mptcp: join: avoid backquotes
As explained on ShellCheck's wiki [1], it is recommended to avoid
backquotes `...` in favour of parenthesis $(...):

> Backtick command substitution `...` is legacy syntax with several
> issues.
>
> - It has a series of undefined behaviors related to quoting in POSIX.
> - It imposes a custom escaping mode with surprising results.
> - It's exceptionally hard to nest.
>
> $(...) command substitution has none of these problems, and is
> therefore strongly encouraged.

1e777bd818 selftests: mptcp: join: clarify local/global vars
Some vars are redefined in different places. Best to avoid this
classical Bash pitfall where variables are accidentally overridden by
other functions because the proper scope has not been defined.

Most issues are with loops: typically 'i' is used in for-loops but if it
is not global, calling a function from a for-loop also doing a for-loop
with the same non local 'i' variable causes troubles because the first
'i' will be assigned to another value. To prevent such issues, the
iterator variable is now declared as local just before the loop. If it
is always done like this, issues are avoided.

To distinct between local and non local variables, all non local ones
are defined at the beginning of the script. The others are now defined
with the "local" keyword.

c7d49c033d selftests: mptcp: join: alt. to exec specific tests
Running a specific test by giving the ID is often what we want: the CI
reports an issue with the Nth test, it is reproducible with:

  ./mptcp_join.sh N

But this might not work when there is a need to find which commit has
introduced a regression making a test unstable: failing from time to
time. Indeed, a specific test is not attached to one ID: the ID is in
fact a counter. It means the same test can have a different ID if other
tests have been added/removed before this unstable one.

Remembering the current test can also help listing failed tests at the
end.

ae7bd9ccec selftests: mptcp: join: option to execute specific tests
Often, it is needed to run one specific test.

There are options to run subgroups of tests but when only one fails, no
need to run all the subgroup. So far, the solution was to edit the
script to comment the tests that are not needed but that's not ideal.

Now, it is possible to run one specific test by giving the ID of the
tests that are going to be validated, e.g.

  ./mptcp_join.sh 36 37

This is cleaner and saves time.

Technically, the reset* functions now return 0 if the test can be
executed. This naturally creates sections per test in the code which is
also helpful to understand what a test is exactly doing.

3afd0280e7 selftests: mptcp: join: define tests groups once
When adding a new tests group, it has to be defined in multiple places:

- in the all_tests() function
- in the 'usage()' function
- in the getopts: short option + what to do when the option is used

Because it is easy to forget one of them, it is useful to have to define
them only once.

Note: only using an associative array would simplify the code but the
entries are stored in a hashtable and iterating over the different items
doesn't give the same order as the one used in the declaration of this
array. Because we want to run these tests in the same order as before, a
"simple" array is used first.

65466904b0 tcp: adjust TSO packet sizes based on min_rtt
Back when tcp_tso_autosize() and TCP pacing were introduced,
our focus was really to reduce burst sizes for long distance
flows.

The simple heuristic of using sk_pacing_rate/1024 has worked
well, but can lead to too small packets for hosts in the same
rack/cluster, when thousands of flows compete for the bottleneck.

Neal Cardwell had the idea of making the TSO burst size
a function of both sk_pacing_rate and tcp_min_rtt()

Indeed, for local flows, sending bigger bursts is better
to reduce cpu costs, as occasional losses can be repaired
quite fast.

This patch is based on Neal Cardwell implementation
done more than two years ago.
bbr is adjusting max_pacing_rate based on measured bandwidth,
while cubic would over estimate max_pacing_rate.

/proc/sys/net/ipv4/tcp_tso_rtt_log can be used to tune or disable
this new feature, in logarithmic steps.

Tested:

100Gbit NIC, two hosts in the same rack, 4K MTU.
600 flows rate-limited to 20000000 bytes per second.

Before patch: (TSO sizes would be limited to 20000000/1024/4096 -> 4 segments per TSO)

b0de0cf4f5 tcp: autocork: take MSG_EOR hint into consideration
tcp_should_autocork() is evaluating if it makes senses
to not immediately send current skb, hoping that
user space will add more payload on it by the
time TCP stack reacts to upcoming TX completions.

If current skb got MSG_EOR mark, then we know
that no further data will be added, it is therefore
futile to wait.

SOF_TIMESTAMPING_TX_ACK will become a bit more accurate,
if prior packets are still in qdisc/device queues.

c01e605904 Merge branch 'net-fungible-fix-errors-when-config_tls_device-n'
Dimitris Michailidis says:

====================
net/fungible: fix errors when CONFIG_TLS_DEVICE=n

This pair of patches fix compile errors in funeth when
CONFIG_TLS_DEVICE=n. The errors are due to symbols that are not defined
in this config but are used in code guarded by
"if (IS_ENABLED(CONFIG_TLS_DEVICE) ..."

One option is to place this code under preprocessor guards that will
keep the compiler from looking at the code. The option adopted here is
to define the offending symbols also when CONFIG_TLS_DEVICE=n.

The first patch does this for two functions in tls.h.
The second does the same for driver symbols and makes tls.h inclusion
unconditional.

91ec779247 e1000e: Print PHY register address when MDI read/write fails
There is occasional suspend error from e1000e which blocks the
system from further suspending. And the issue was found on
a WhiskeyLake-U platform with I219-V:

[   20.078957] PM: pci_pm_suspend(): e1000e_pm_suspend+0x0/0x780 [e1000e] returns -2
[   20.078970] PM: dpm_run_callback(): pci_pm_suspend+0x0/0x170 returns -2
[   20.078974] e1000e 0000:00:1f.6: PM: pci_pm_suspend+0x0/0x170 returned -2 after 371012 usecs
[   20.078978] e1000e 0000:00:1f.6: PM: failed to suspend async: error -2

According to the code flow, this might be caused by broken MDI read/write
to PHY registers. However currently the code does not tell us which
register is broken. Thus enhance the debug information to print the
offender PHY register. So the next the issue is reproduced, this
information could be used for narrow down.

e18058ea99 net: dsa: microchip: ksz9477: implement MTU configuration
This chips supports two ways to configure max MTU size:
- by setting SW_LEGAL_PACKET_DISABLE bit: if this bit is 0 allowed packed size
  will be between 64 and bytes 1518. If this bit is 1, it will accept
  packets up to 2000 bytes.
- by setting SW_JUMBO_PACKET bit. If this bit is set, the chip will
  ignore SW_LEGAL_PACKET_DISABLE value and use REG_SW_MTU__2 register to
  configure MTU size.

Current driver has disabled SW_JUMBO_PACKET bit and activates
SW_LEGAL_PACKET_DISABLE. So the switch will pass all packets up to 2000 without
any way to configure it.

By providing port_change_mtu we are switch to SW_JUMBO_PACKET way and will
be able to configure MTU up to ~9000.
