Looks like mac80211 on an STA does that for frames with a
multicast destination (to prevent getting the own multicast
packets echo'd back once the AP rebroadcasts them, I guess). E.g.
ap-isolation + bridge-hairpin without multicast-to-unicast works
fine. So maybe the simple fix for the multicast-to-unicast patch
is sufficient.

The unicast-to-multicast patch mangled the destination to a
unicast one and mac80211 does not seem to consider their source

Going to make and try a patch for the bridge now.

Cheers, Linus
