Well, the Multicast Listener Report seems that skb->data != skb->nh.ipv6h

skb->data == skb->nh.ipv6h like IPv4 netfilter modules.

folks, is this wrong or bad asumption ? If so, I'll fix this problem in
many modules as follows.

Sorry for getting back to this so late, I must have missed it at the
time. Anyway, I think it would be safer to restore netfilters assumption
by doing something like this patch. If everyone is fine with it I'm
going to add it to my pending netfilter patches for 2.6.13.
