monitor mode

Hi everyone,

I have questions about the monitor mode of atmel chipset. From iwpriv, I
saw "monitor          (8BF2) : set   2 int   & get   0", does it mean
monitor mode is supported by the firmware and driver?

However, I couldn't find useful information on using iwpriv to change the
modes, could someone please explain the numbers (x, y) in "#iwpriv wlan0
monitor x y"?

The last question is that I want to use ethereal to log the events of
scan/authentication/association as well as the dhcp packets, how do I
monitor all these?

Btw, my machine has Fedora 3 and Linksys WUSB11 v2.8. Any comments would
be appriciated!

Thanks!
