We may be able to skip adding or deleting local address which is identical to dev_addr in bridge code. Having said that I feel like drivers should ensure not to remove their permanent address even when the same address is removed from the uc list, since currently it is not prohibited to do that kind of admin operation through bridge command (bridge fdb add|del self). Note that "bridge fdb ... self" is a command which modifies device's uc filter, not modify bridge's fdb entries. -- Toshiaki Makita
