I debugged this a long time ago. The problem is that firmware's CMD_JOIN only works if bssid is correct one. I remember trying ff:ff:ff:ff:ff:ff, but that didn't work for some reason. The join command needs to be sent before association, otherwise transmission won't work at all. And if I use a random bssid the firmware will filter the replies. But I tested this a long time ago, I might remember something wrong. I was thinking a hack which would get bssid from association frames and then send CMD_JOIN, before the association frame. IMHO no need to change mac80211 because of this old hardware.
