[CFT] if_ath updates - ar5416 (macbook pro, etc)

[Adrian Chadd]

Hi everyone,

I've just merged in some changes to the noise floor (NF) internal
calibration and NF CCA (clear channel assessment) programming. This
may (slightly) improve AR5416/AR9160 behaviour in both AP and station
mode in noisy/busy conditions.

I've only really tested this in AP mode as I don't (currently) have a
laptop or desktop with an AR5416 or AR9160 in it.

Thanks!


Adrian
