bridge: add per-port broadcast flood flag
Support for l2 multicast flood control was added in commit b6cb5ac8331b ("net: bridge: add per-port multicast flood flag"). It allows broadcast as it was introduced specifically for unknown multicast flood control. But as broadcast is a special case of multicast, this may also need to be disabled. For this purpose, introduce a flag to disable the flooding of received l2 broadcasts. This approach is backwards compatible and provides flexibility in filtering for the desired packet types.
