Merge branch 'mlxsw-unified-bridge-conversion-part-2'

Ido Schimmel says:

====================
mlxsw: Unified bridge conversion - part 2/6

This is the second part of the conversion of mlxsw to the unified bridge
model. Part 1 was merged in commit 4336487e ("Merge branch
'mlxsw-unified-bridge-conversion-part-1'") which includes details about
the new model and the motivation behind the conversion.

This patchset does not begin the conversion, but rather prepares the code
base for it.

Patchset overview:

Patch #1 removes an unnecessary field from one of the FID families.

Patches #2-#7 make various improvements in the layer 2 multicast code,
making it more receptive towards upcoming changes.

Patches #8-#10 prepare the CONFIG_PROFILE command for the unified bridge
model. This command will be used to enable the new model in the last
patchset.

Patches #11-#13 perform small changes in the FID code, preparing it for
upcoming changes.
