ieee80211 scan function starting point

[Farhan Khan]

Hi all,

I am trying to get the "ifconfig wlan0 list scan" command to display 
local access points. I am fairly certain I have the "up" part working 
(loading firmware, turning it on) but the scan portion does not yet.

I am trying to identify what functions I might have missed with dtrace, 
but I do not know where to start off and the probes are too rapid to 
identify where it starts when I run the "ifconfig" command. I am fairly 
certain it originates in ieee80211 and kicks that off to the driver, but 
I cannot easily identify where.

Does anyone know where? Thank you.

Farhan
