I was considering default behavior here for drivers that do not provide this information, ie. drivers not supporting 4-way handshake offload. So wpa_supplicant just looks for the PORT_AUTHORIZED attribute and deals with it without need for checking 4-way handshake offload is supported. Regards, Arend
