Hello Linus,

I gave it a try - but there seems something off. What I did is:
 * apply your patches on 3b38a80 - multicast was enabled by default
 * start 2 VMs directly connected
 * ping6 -I bat0 ff02::1

I only got a reply locally, but not from the peer. When I disabled
multicast, I got two replies from the local host and the peer.

As far as I have tracked the problem down, it appears that
batadv_mcast_forw_mode() returns 1 correctly, but the packet is dropped
later in the process - I would guess that this happens in
batadv_send_generic_unicast_skb() where we try to select the gateway
when the destination mac is multicast instead of looking it up in the
tt table. But I leave the details to you. :)

The rest looks good, but I'll review more deeply again when it's
actually working. It does compile without problems now.

Cheers,
	Simon
