Subject: Get/set Sensitivity for a radio?

Hello!

I'm having no luck finding where sensitivity is set in
net/mac80211. Anyone know something to grep for?

Thanks,
Ben

I'm messing with ath9k mostly. Just trying to probe some values
for reporting as of now. In the old days, seems you could
set the sensitivity for madwifi though..could help in some
cases...

Thanks,

Ok, thanks.

If you happen to know some of the related tunables, I'd like
to take a look at them, at least.

Thanks,

It doesn't make sense to try to add a single 'sensitivity' knob. There
are many different radio parameters that are related to that, some
calibrated, some configured - madwifi never had anything useful for that
either.

I am not sure mac80211 deal with sensitivity if it's what you referring
(at least not I am aware of).

in iwlwifi, driver and uCode take care of sensitivity calibration.
