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?

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?
Or.
