>Description:
The "ifconfig list scan" command does not work in adhoc mode if the channel was manually set with "ifconfig wlanX channel Y"
It only works if the channel was not configured.
>How-To-Repeat:
ifconfig wlan0 create wlandev ath0 wlanmode adhoc
ifconfig wlan0 bssid 66:98:40:46:b7:0a up
ifconfig wlan0 list scan

------------------------------------------------------------------
Now lock the channel, after that "list scan" gives no more output.
------------------------------------------------------------------
ifconfig wlan0 down
ifconfig wlan0 channel 13 up
ifconfig wlan0 list scan
------------------------------------------------------------------
Remove the channel selection and it works again
------------------------------------------------------------------
ifconfig wlan0 down
ifconfig wlan0 channel -
ifconfig wlan0 up
