So the only solution I could think of for now is excluding DHCPv6 from multicast feature in TX of the originator... (in batadv_mcast_forw_mode_check_ipv6(), adding excludes for ff02::1:2 and ff05::1:3).
And there is also no way for a random node in the mesh to figure out if two or more other nodes share the same LAN via BLA, right?
That would have been the other option, to avoid sending a multicast-in-unicast packet via the multicast feature to multiple such nodes in the first place.
