For more generalization, I think that "group_head" should replace
"gaddr" and related struct members, and "group_head" should allow
multicast addresses, and then multicast join/leave should be done.

I've trying to replace "gaddr" with "defaut destination" as vxlan_rdst
(but it can be set single destination yet).
I'll send the patch soon.  Could you review it?

Thanks.
