OK, I think I'm with you now... you suggest to avoid our direction of
implementing promiscuous multicast mode which is applied by today's
bridge, macvtap and friends by fixing these elements to support non
promisc multicast mode, yep, sure, sounds as win/win, which will
eliminate the need to do IGMP snooping in the driver.
