In the debug log I see the line:
ath0: ieee80211_scan_update: no scanner suppport for mode 8
 From source code I see that mode 8 is IEEE80211_M_MONITOR.
As I understand in 'monitor' mode no packets are being sent or received.
When I try to turn it off with 'ifconfig ath0 -monotor' interface  
still seems to stay in monitor mode.

Why wouldn't -monitor turn monitor mode off?
