Yeah, that'd be a bug, and I can't find any such assignment. In fact, mac80211 doesn't contain any assignment to hw_key_idx or to a 1-4 key_idx from hw_key_idx. Never mind the fact that the tx_control member could be called hw_key_idx as well... In any case, for the problem at hand, I wouldn't mind increasing hw_key_idx to a u16 all the way through, or pass the key_conf pointer instead. johannes
