iwspy functionality w/ prism54

Since there is currently no iwspy functionality in the Prism driver, we 
(myself and/or colleagues) are considering implementing it ourselves. 
We require the ability to collect link quality stats on the individual 
nodes in an ad hoc network.

However, there does not seem to be any clue in the driver as to how one 
would obtain the link quality data.  It appears that the driver is 
obtaining link quality stats in AP mode by querying it via the BSSID, 
but I'm guessing that wouldn't help for ad hoc mode.  Does anyone know 
how one would go about obtaining the data?  Is there a programming 
manual for this chip that is publicly available?

Thanks,
Bob Farmer
