This patch will break multicast forwarding using the pim6 daemon. This daemon creates an interface called pim6reg which is not MULTICAST enabled but needs to be configred by addrconf to get ff00::/8 and fe80::/64 routes. This is required since the route lookup process has been enforced to strictly match input interfaces for linklocal and multicast packets.
