It does seem a little broad notification type. I've checked over
all the currently defined NETDEV notifiers, and it seems that
NETDEV_NOTIFY_PEERS may be a better option to use when bridge
has a potential topology change.

Currently it is only used in ipv4/devinet.c: where it is used to issue
a gratuitous ARP.
