Finally, I got around to looking into this problem, I apologise for the delay! The issue turns out to be that mostly we were working with asymmetric devices (2x3) and there this worked ... otherwise not. The original mac80211 patch is still needed to fix it, but it's not sufficient, iwlagn also needs to be fixed. Tested against an ath9k AP (3x3) and also against the same ath9k AP with hostapd hacked to pretend it is 1x1. johannes -- 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
