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

This patchset contains various small fixes for mlxsw.

Patch #1 fixes a warning generated by switchdev core when the driver
fails to insert an MDB entry in the commit phase.

Patches #2-#4 fix a warning in check_flush_dependency() that can be
triggered when a work item in a WQ_MEM_RECLAIM workqueue tries to flush
a non-WQ_MEM_RECLAIM workqueue.

It seems that the semantics of the WQ_MEM_RECLAIM flag are not very
clear [1] and that various patches have been sent to remove it from
various workqueues throughout the kernel [2][3][4] in order to silence
the warning.

These patches do the same for the workqueues created by mlxsw that
probably should not have been created with this flag in the first place.

Patch #5 fixes a regression where an IP address cannot be assigned to a
VRF upper due to erroneous MAC validation check. Patch #6 adds a test
case.

Patch #7 adjusts Spectrum-2 shared buffer configuration to be compatible
with Spectrum-1. The problem and fix are described in detail in the
commit message.

Please consider patches #1-#5 for 5.0.y. I verified they apply cleanly.
