ip/ipconfig: ask devip to delete expired ipv6 prefixes (thanks arne) In addition to removing expired default routes, ask devip to clean out expired addresses as well. In the future, devip might do something more sophisticated than just checking the valid life time like also considering if the address is still begin used by active connections.
