Sure, I'll add that back.  I read the patent but I'm not sure it applies
100%, it also talks at the end about keeping the rx antennas connected
and measuring the noise in the environment instead of just the thermal
noise.  I guess one way to know for sure is to hit it with noise and
look at the resulting values.

Yeah, I looked at that, madwifi/legacy-hal also set it
(just the EEPROM value for the threshold bits) before doing the false
detect backoff stuff.
