We cannot move all this code to switchdev core, because switchdev is
stateless, so there is no place to register the netdevice notifier(s).

But it might be possible to provide a generic switchdev_netdevice_event
helper, using new switchdev operations to check a port device, and
add/del upper devices. I'll think about that.
