[PATCH net-next RFC 07/12] net: dsa: Add support for querying supported bridge flags

[Arkadi Sharshevsky]

The DSA drivers do not support bridge flags offload. Yet, this attribute
should be added in order for the bridge to fail when one tries set a
flag on the port, as explained in commit dc0ecabd6231 ("net: switchdev:
Add support for querying supported bridge flags by hardware").
