To be clear, what I'm preparing for that second series is to:
- move all of br_vlan_replay, br_mdb_replay into br_switchdev.c
- consistently name all functions to br_switchdev_*
- refactor the switchdev logic from br_mdb_notify into a new
br_switchdev_mdb_notify for symmetry with fdb_notify and
br_switchdev_fdb_notify
But I'm still working on it, because the VLAN and IGMP snooping code
is conditionally compiled, making it a bit harder :)

So the current placement of the br_fdb_replay function is not bad,
according to the follow-up changes I am going to make.
