Right, that's the situation I had in mind. If the number of
transmissions were growing too large somehow to limit them.

On the other hand, now that you reiterate this maybe this is such
a minor case that it is not worth bothering for now.

Hm, I think I'll remove these intermediate limit checks to
simplify things. So that we only check once in batadv_mcast_forw_mode()
for the mcast_fanout.
