   The reason is that (in af_packet.c) packet_notifier(NETDEV_DOWN) sets
   sk->err to ENETDOWN, but packet_notifier(NETDEV_UP) doesn't clear it.
   Is this behaviour deliberate?

Yes the behavior is deliberate.  You want to be aware of the
event.  Just because the opposite event has occurred afterwards
doesn't mean the first event didn't happen :-)
