Hi, Just as side information for other readers: Alexandre is looking into the problem of rt2500usb/rt73usb and possibly other USB drivers, that they cannot report the ACK status of frames to mac80211 which is problematic for hostapd. > I'm trying to catch Acknowlegement frames in the mac80211, but I don't > managed to. Thus I'm wondering if they follow another path than the > frames that aren't control ones? Have you made sure that mac80211 has called the configure_filter() callback function with the FIF_CONTROL flag enabled?
