Merge branch 'mlxsw-fixes' 

Ido Schimmel says:

====================
mlxsw: Various fixes

This patchset contains small fixes in mlxsw and one fix in the bridge
driver.

Patches #1-#4 perform small adjustments in PCI and FID code following
recent tests that were performed on the Spectrum-2 ASIC.

Patch #5 fixes the bridge driver to mark FDB entries that were added by
user as such. Otherwise, these entries will be ignored by underlying
switch drivers.

Patch #6 fixes a long standing issue in mlxsw where the driver
incorrectly programmed static FDB entries as both static and sticky.

Patches #7-#8 add test cases for above mentioned bugs.

Please consider patches #1, #2 and #4 for stable.
====================
