What about things like neigh_sysctl_register which expects nonempty dev
name or rtnetlink_event which sends a RTM_NEWLINK event (I doubt that
listeners are prepared for nonempty dev name)?

Also, if the interface has ifindex assigned it is accessible from user
space (although it's unlikely anybody would call anything on it) - what
should be the correct result of e.g. SIOCGIFNAME?

Thanks,

 Jiri
