Merge branch 'mlxsw-next'
Ido Schimmel says: ==================== 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. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
