[net-next,4/4] batman-adv: Act on NETDEV_*_TYPE_CHANGE events
Commit Message
A network interface can change type. It may change from a type which
batman does not support, e.g. hdlc, to one it does, e.g. hdlc-eth.
When an interface changes type, it sends two notifications. Handle
these notifications.
