I still think you should add a wiphy flag and advertise it in nl80211 to advertise and request this behaviour. That will allow hostapd (and mac80211 in IBSS mode) to not reply to probe requests when they aren't filtered out by the device, and will allow hostapd/wpa_s to also restrict its operation to non-P2P etc. as Jouni pointed out. For P2P then that will have to be extended more I guess, and the firmware functionality be improved -- or even disabled. johannes
