DHCPv6 destination address check

As described in RFC3315 §15 any solicit, confirm, rebind or information request message is discarded if the destination address is unicast
Likewise any request (§18.2.1), renew (§18.2.3), release (§18.2.6) or decline (§18.2.7) message is discarded and the server replies with the status code use multicast.
