I intentionally wanted to keep the implementation outside of mac80211,
because there are other scenarios where this could be useful.
I might have a dumb AP with no IGMP snooping capabilities connected to
an Ethernet interface, and with this implementation I can simply enable
multicast->unicast translation on the Ethernet device.
