The addition of routable multicast TX handling introduced a bug/regression for packets with a link-local multicast destination: These packets would be sent to all batman-adv nodes with a multicast router and to all batman-adv nodes with an old version without multicast router detection.
This even disregards the batman-adv multicast fanout setting, which can potentially lead to an unwanted, high number of unicast transmissions or even congestion.
Fixing this by avoiding to send link-local multicast packets to nodes in the multicast router list.

It fails to build. See attachment.
I will fix this myself.
Kind regards, Sven
