Hrm, on the other hand, if a querier is actually on one of the
other STAs then mac80211 would have to forward the report there.
Which would mean either needing query-snooping in mac80211 (or
netdev in general) or interaction between mac80211 and the
bridge-snooping code.

I really hate this IGMPv2/MLDv1 report suppression...
(that's where all the complexity in the batman-adv multicast
optimizations came from, too)
