Subject[PATCH net-next v2] net: bridge: switchdev: pass more port flags to drivers
Date
These 3 port flags: BR_HAIRPIN_MODE, BR_MULTICAST_TO_UNICAST, and
BR_ISOLATED, affect the data path and should be handled by switchdev
drivers.

Add them to BR_PORT_FLAGS_HW_OFFLOAD so they can be passed down to
the drivers.
