And according Hmm, if the firmware sends you a MACREG_INT_CODE_WMM_STATUS_CHANGE but you're sure that the beacons don't change, then the firmware seems to be buggy. Not sure if Marvell got sane and opened up their support for no-NDA-holders, but you could try and file a bug there. And we should look into the libertas driver if we always loose a packet whenever we get a MACREG :-) Greetings, Holger -- http://www.holgerschurig.de
