ath9k_hw: start building an abstraction layer for hardware routines
ath9k supports the AR5008, AR9001 and AR9002 family of Atheros chipsets, all 802.11n. The new breed of 802.11n chips, the AR9003 family will be supported as well soon. To help with its support we're going to add a few callbacks for hardware routines which differ considerably instead of adding branch checks for the revision at runtime. Signed-off-by: Luis R. Rodriguez <lrodriguez@atheros.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
