Merge branch 'mlxsw-Various-updates'

Ido Schimmel says:

====================
mlxsw: Various updates

Patches 1-3 update the driver to use a new firmware version. Due to a
recently discovered issue, the version (and future ones) does not
support matching on VLAN ID at egress. This is enforced in the driver
and reported back to the user via extack.

Patch 4 adds a new selftest for the recently introduced algorithmic
TCAM.

Patch 5 converts the driver to use SPDX identifiers.

Patches 6-7 fix a bug in ethtool stats reporting and expose counters for
all 16 TCs, following recent MC-aware changes that utilize TCs 8-15.
