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

This patchset contains various fixes for mlxsw.

Patch #1 fixes a race condition in a selftest. The race and fix are
explained in detail in the changelog.

Patch #2 re-adds a link mode that was wrongly removed, resulting in a
regression in some setups.

Patch #3 fixes a race condition in route installation with nexthop
objects.

Please consider patches #2 and #3 for stable.
