When did you test this patch last time on net-next?
Asking because when a port joins a VLAN-aware bridge, it will replay the
FDB entries towards the bridge, which include a VLAN-unaware FDB entry
with VID 0, and a VLAN-aware one with the bridge's default_pvid.
If you return -EINVAL, that br_fdb_replay call will fail and you will
fail to join the bridge.
