Add some PLCP thresholds from Linux iwlwifi driver in preparation for 

working on some RF tuning issues.

The linux iwlwifi driver has these thresholds which they use to see
if there are PLCP errors over a certain interval.  If they hit this,
they trigger a single-channel (different from active channels!)
scan to retune the RF front-end.
