Merge branch 'mlxsw-Add-devlink-trap-support'
Ido Schimmel says: ==================== mlxsw: Add devlink-trap support This patchset adds devlink-trap support in mlxsw. Patches #1-#4 add the necessary APIs and defines in mlxsw. Patch #5 implements devlink-trap support for layer 2 drops. More drops will be added in the future. Patches #6-#7 add selftests to make sure that all the new code paths are exercised and that the feature is working as expected. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
