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. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
