Merge branch 'mlxsw-Two-small-fixes' 

Ido Schimmel says:

====================
mlxsw: Two small fixes

Patch #1 from Jiri fixes an issue specific to Spectrum-2 where the
insertion of two identical flower filters with different priorities
would trigger a warning.

Patch #2 from Amit prevents the driver from trying to configure a port
with a speed of 56Gb/s and autoneg off as this is not supported and
results in error messages from firmware.

Please consider patch #1 for stable.
