Vladimir Oltean says:

====================
Cleanup in brport flags switchdev offload for DSA

The initial goal of this series was to have better support for
standalone ports mode on the DSA drivers like ocelot/felix and sja1105.
This turned out to require some API adjustments in both directions:
to the information presented to and by the switchdev notifier, and to
the API presented to the switch drivers by the DSA layer.
====================
