Maybe miniport driver modify/corrupts ethernet packets somehow. Try to pick packets transferred in air (via another card with working monitor mode). Tcpdump on wlan(0) can not help because that is what FreeBSD sends to ndis and not what driver sends, so with your already reported output we can only see outcome of bug, not real source of it. Try code from gitorious, if something come up with bootverbose I could add bunch of DEBUG printfs. --=20 Paul B Mahol
