I can't think of anything that would be specifically useful for 802.11s right now, and we can always extend the statistics in the future. One case where this might be useful is if the driver has a limited number of station slots, the MPM could monitor neighbor stations for a more "suitable" peer candidate, but your existing stats should cover that. Turning on this feature would add some sort of (internal to mac80211) monitor interface, or just disable all frame filters on a given PHY?
