Instead of latching onto the OGM period, this patch introduces a worker dedicated to multicast TT and TVLV updates. The reasoning is, that upon roaming especially the translation table should be updated timely to minimize connectivity issues. With BATMAN V, the idea is to greatly increase the OGM interval to reduce overhead. Unfortunately, right now this could lead to a bad user experience if multicast traffic is involved. Therefore this patch introduces a fixed 500ms update interval for multicast TT entries and the multicast TVLV.
