====================
mlxsw: Various updates

This patchset contains various updates to the mlxsw driver and related
selftests.

Patches #1-#5 contain various updates to mlxsw selftests. The most
significant change is the conversion of the DCB selftests to use the new
iproute2 DCB support.

Patches #6-#9 contain mostly trivial changes to the driver itself. No
user facing changes.

Patches #10-#11 remove support for SwitchX-2 and SwitchIB ASICs that did
not see any updates in the last 4-5 years and will not see any in the
future. See individual commit messages for detailed explanation as to
why it is OK to remove these drivers from the kernel.
