commit 6db6f0eae6052b70885562e1733896647ec1d807 upstream.
Implements an optional, per bridge port flag and feature to deliver multicast packets to any host on the according port via unicast individually. This is done by copying the packet per host and changing the multicast destination MAC to a unicast one accordingly.
multicast-to-unicast works on top of the multicast snooping feature of the bridge. Which means unicast copies are only delivered to hosts which are interested in it and signalized this via IGMP/MLD reports previously.
This feature is intended for interface types which have a more reliable and/or efficient way to deliver unicast packets than broadcast ones (e.g. wifi).

This looks like a new feature rather than a fix, why does it need to go to -stable?
Yeah :/
I'm not very good with networking stuff and it shows.
I percieved it as something else when I picked it out, now I see that it requires a flag set on the bridge which is not gonna be done without some other changes setting it. Let's drop it.
Thanks, Linus Walleij
