Subject: ath9k_hw: always enable 5 GHz fast clock for AR9280
X-Git-Url: https://openfabrics.org/gitweb/?a=commitdiff_plain;h=a949b1725c38775fb869d24433f13d2d104de145;p=~shefty%2Frdma-dev.git

ath9k_hw: always enable 5 GHz fast clock for AR9280

All devices support this, but some disable it using an EEPROM flag
for some reason. Improves 5 GHz performance on those devices.
