interface since it makes much trouble everywhere. Instead, we understand secondary addresses as subinterfaces. - In case interface addresses or basic flags change, we simply convert it to a down/up sequence. - Implemented the universal neighbour cache. (Just forget what did previous includes say of neighbour caching, this one is brand new.)
