Please don't top post on netdev@.
The current code works correctly, my question to Pablo was more about if the warn
can still be triggered by adding a BR_FDB_LOCAL fdb and setting bridge
promisc on, then we'll hit that codepath with promisc == false and it's
kind of correct because traffic would've been passed up anyway, but the
promisc flag can be actually set on the device..
