ipv6 sends a RTM_DELLINK netlink message on both events: NETDEV_DOWN,
NETDEV_UNREGISTER. Corrected by sending RTM_NEWLINK on NETDEV_DOWN event
and RTM_DELLINK on NETDEV_UNREGISTER event.
Why would we indicate that a new device has appeared on NETDEV_DOWN?
I don't see any sense in saying "RTM_NEWLINK" for a removal, it's
for additions.
