Yes, for iwlwifi that's actually a change. For everyone else (not setting BUFF_MMPDU_TXQ or STA_MMPDU_TXQ) it already is since it goes directly to ->tx() and from there to the hardware queue(s). > With all the possibilities for badness (such as the > ability of starving all other queues) that carries with it.

Well, there's just not that many management frames to start with? And only wpa_supplicant (or root in general) can create them. So I don't think we need to worry about that yet. With QoS-mgmt frames we might eventually want to think about that, but even there I'd say we never really want to drop them. johannes
