With this patch a multicast packet is not always simply flooded anymore, the behaviour for the following cases is changed to reduce unnecessary overhead: If all nodes within the horizon of a certain node have signalized multicast listener announcement capability then an IPv6 multicast packet with a destination of IPv6 link-local scope (excluding ff02::1) coming from the upstream of this node... * ...is dropped if there is no according multicast listener in the translation table, * ...is forwarded via unicast if there is a single node with interested multicast listeners * ...and otherwise still gets flooded.
