From: Ido Schimmel <idosch@nvidia.com>

This patchset contains various updates to mlxsw selftests.

Patch #1 replaces open-coded compatibility checks with dedicated
helpers. These helpers are used to skip tests when run on incompatible
machines.

Patch #2 avoids spurious failures in some tests by using permanent
neighbours instead of reachable ones.

Patch #3 reduces the run time of a test by not iterating over all the
available trap policers.

  selftests: mlxsw: Use permanent neighbours instead of reachable ones
  selftests: mlxsw: Reduce test run time

From: Petr Machata <petrm@nvidia.com>

A number of mlxsw-specific selftests currently detect whether they are run
on a compatible machine, and bail out silently when not. These tests are
however done in a somewhat impenetrable manner by directly comparing PCI
IDs against a blacklist or a whitelist, and bailing out silently if the
machine is not compatible.

Instead, add a helper, mlxsw_only_on_spectrum(), which allows specifying
the supported machines in a human-readable manner. If the current machine
is incompatible, the helper emits a SKIP message and returns an error code,
based on which the caller can gracefully bail out in a suitable way. This
allows a more readable conditions such as:

	mlxsw_only_on_spectrum 2+ || return

Convert all existing open-coded guards to the new helper. Also add two new
guards to do_mark_test() and do_drop_test(), which are supported only on
Spectrum-2+, but the corresponding check was not there.

From: Ido Schimmel <idosch@nvidia.com>

The nexthop objects tests configure dummy reachable neighbours so that
the nexthops will have a MAC address and be programmed to the device.

Since these are dummy reachable neighbours, they can be transitioned by
the kernel to a failed state if they are around for too long. This can
happen, for example, if the "TIMEOUT" variable is configured with a too
high value.

Make the tests more robust by configuring the neighbours as permanent,
so that the tests do not depend on the configured timeout value.

Instead of iterating over all the available trap policers, only perform
the tests with three policers: The first, the last and the one in the
middle of the range. On a Spectrum-3 system, this reduces the run time
from almost an hour to a few minutes.
