In the last few weeks I used a wpa_supplicant with my patches for tx and rx over nl80211 control port and sometimes observed longer time to successful connection than without these patches. I think that this is a result of wpa_supplicant using SOCK_WIFI_STATUS when transmitting EAPOL frames over AF_PACKET sockets and using a fast retransmit, if the Wi-Fi ack is not observed timely. So the question here is, should we add an analog feature for tx over nl80211 control port? I think of a control_port_tx_status message with a cookie delivered to user-space. Regards, Markus
