Does rate control (btw, remove the duplicated "control" from the text) algorithm have knowledge of whether PTK has already been configured? There is going to be a somewhat unfortunate timing issue with trying to set up aggregation before 4-way handshake has been completed if 802.11w is used (Action frames are dropped before the keys are set). Something in the system (either the request or mac80211's action on the request) would need to be delayed until the keys are in place in such a case. -- Jouni Malinen PGP id EFC895FA -- To unsubscribe from this list: send the line "unsubscribe linux-wireless" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
