I see the rt2x00 drivers do not have iwspy support.[/quote3vkc6ckf]
That is correct.
Is this slated to be available anytime soon?[/quote3vkc6ckf]
Nope, in fact the entire iwspy interface in the kernel is pending to be removed entirely.
If not, is it considered very difficult to add?[/quote3vkc6ckf]
Extremely, since the interace is already deprecated.
Our device would mostly be used in ad-hoc mode and it would be nice to know the signal strength of the other node.[/quote3vkc6ckf]
You should take a look at the nl80211 interface instead of the ancient and deprecated interfaces.
