I assume what's left is to add macvlan_hash_xxx multicast logic to map/unmap multicast groups to what macvlan devices want to receive them and this way the flooding can be removed, correct? > The device can just flood all multicast packets, since the filtering is done on the receive path anyway. for each multicast packet, macvlan_broadcast is invoked and calls skb_clone/ netif_rx for each device, now a smart scheme that takes into account (hash) the multicast list of the different macvlan devices would save the skb_clone call, isn't it?
