Merge branch 'mlxsw-L3-HW-stats-improvements'

Ido Schimmel says:

====================
mlxsw: L3 HW stats improvements

While testing L3 HW stats [1] on top of mlxsw, two issues were found:

1. Stats cannot be enabled for more than 205 netdevs. This was fixed in
commit 4b7a632ac4e7 ("mlxsw: spectrum_cnt: Reorder counter pools").

2. ARP packets are counted as errors. Patch #1 takes care of that. See
the commit message for details.

The goal of the majority of the rest of the patches is to add selftests
that would have discovered that only about 205 netdevs can have L3 HW
stats supported, despite the HW supporting much more. The obvious place
to plug this in is the scale test framework.

The scale tests are currently testing two things: that some number of
instances of a given resource can actually be created; and that when an
attempt is made to create more than the supported amount, the failures
are noted and handled gracefully.

However the ability to allocate the resource does not mean that the
resource actually works when passing traffic. For that, make it possible
for a given scale to also test traffic.

To that end, this patchset adds traffic tests. The goal of these is to
run traffic and observe whether a sample of the allocated resource
instances actually perform their task. Traffic tests are only run on the
positive leg of the scale test (no point trying to pass traffic when the
expected outcome is that the resource will not be allocated). They are
opt-in, if a given test does not expose it, it is not run.

The patchset proceeds as follows:

- Patches #2 and #3 add to "devlink resource" support for number of
allocated RIFs, and the capacity. This is necessary, because when
evaluating how many L3 HW stats instances it should be possible to
allocate, the limiting resource on Spectrum-2 and above currently is
not the counters themselves, but actually the RIFs.

- Patch #6 adds support for invocation of a traffic test, if a given scale
tests exposes it.

- Patch #7 adds support for skipping a given scale test. Because on
Spectrum-2 and above, the limiting factor to L3 HW stats instances is
actually the number of RIFs, there is no point in running the failing leg
of a scale tests, because it would test exhaustion of RIFs, not of RIF
counters.

- With patch #8, the scale tests drivers pass the target number to the
cleanup function of a scale test.

- In patch #9, add a traffic test to the tc_flower selftests. This makes
sure that the flow counters installed with the ACLs actually do count as
they are supposed to.

- In patch #10, add a new scale selftest for RIF counter scale, including a
traffic test.

- In patch #11, the scale target for the tc_flower selftest is
dynamically set instead of being hard coded.

selftests: mlxsw: Add a RIF counter scale test

This tests creates as many RIFs as possible, ideally more than there can be
RIF counters (though that is currently only possible on Spectrum-1). It
then tries to enable L3 HW stats on each of the RIFs. It also contains the
traffic test, which tries to run traffic through a log2 of those counters
and checks that the traffic is shown in the counter values.

Like with tc_flower traffic test, take a log2 subset of rules. The logic
behind picking log2 rules is that then every bit of the instantiated item's
number is exercised. This should catch issues whether they happen at the
high end, low end, or somewhere in between.
