In a recent patch I removed functionality for setting a NULL key to the hardware for such STAs and remarked something along the lines of "If hardware needs that, we should not abuse the set_key() function to notify it of new STAs" Seems that is the case with your hardware as well as some atheros hardware the code was initially written for. I'm sure we're willing to consider patches that extend the sta_table_notification() handle to include the MAC address of the station that was added/removed. > There was a whole discussion we led about if rate scale algorithm and > notion of station should separated from the driver or not.
