Especially during off-channel scan user space might be interested
in probe reponse frames along with beacon to build a list
of preferred channel and bssid which could be sent to the stations
around for better spectrum management. Do not drop probe response
frame in AP mode and advertise driver's capability to receive probe
response frame in AP mode to user space.
