You mean BR_PORT_MAB, not BR_PORT_LOCKED, right? AFAIU, "locked" means
drop unknown MAC SA, "mab" means "install BR_FDB_LOCKED entry on port"
(and also maybe still drop, if "locked" is also set on port).

Sad there isn't any good documentation about these flags in the patches
that Hans is proposing.
