Here is my testing in detail. Please help me get injection in aircrack-ng
working with either card, much appreciated.

$ sudo ifconfig wlan0 create wlandev ath0 wlanmode monitor
$ sudo ifconfig wlan0 channel 6 up
$ sudo tcpdump -ni wlan0 -y IEEE802_11_RADIO

Captures.

Works.

Doesn't work. So I can't sniff in ahdemo.
