2016-04-12cfg80211: remove enum ieee80211_bandJohannes Berg
This enum is already perfectly aliased to enum nl80211_band, and the only reason for it is that we get IEEE80211_NUM_BANDS out of it. There's no really good reason to not declare the number of bands in nl80211 though, so do that and remove the cfg80211 one. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2015-08-20ath5k: use DECLARE_EWMAJohannes Berg
This reduces code size slightly (at least on x86/64) while also removing memory consumption by two unsigned long values for each ath5k device. Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: David S. Miller <davem@davemloft.net>

Booleans should not be compared to true or false but be directly tested or tested with !.

2011-11-28ath5k: ath5k_ani_period_restart only touches struct ath5k_ani_stateNick Kossifidis
No need to take ath5k_hw as an argument. Signed-off-by: Nick Kossifidis <mickflemm@gmail.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2011-11-28ath5k: Cleanups v2 + add kerneldoc on all hw functionsNick Kossifidis
No functional changes Add kernel doc for all ath5k_hw_* functions and strcucts. Also do some cleanup, rename ath5k_hw_init_beacon to ath5k_hw_init_beacon_timers, remove an unused variable from ath5k_hw_pcu_init and a few obsolete macros, mostly related to XR.

2011-08-08ath5k: clean up base.h and its usePavel Roskin
Remove unnecessary includes from base.h. Add includes to other files as necessary. Don't include base.h unless needed. Move declarations for functions in base.c from ath5k.h to base.h. Use a better named define to protect base.h against double inclusion. Signed-off-by: Pavel Roskin <proski@gnu.org> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2011-07-20ath5k: merge ath5k_hw and ath5k_softcPavel Roskin
Both ath5k_hw and ath5k_softc represent one instance of the hardware. This duplication is historical and is not needed anymore. Keep the name "ath5k_hw" for the merged structure and "ah" for the variable pointing to it. "ath5k_hw" is shorter than "ath5k_softc", more descriptive and more widely used. Put the combined structure to ath5k.h where the old ath5k_softc used to be. Move some code from base.h to ath5k.h as needed. Remove memory allocation for struct ath5k_hw and the corresponding error handling. Merge iobase and ah_iobase fields.

2010-11-30ath5k: Reset cleanup and generic cleanupNick Kossifidis
* No functional changes * Clean up reset: Introduce init functions for each unit and call them instead of having everything inside ath5k_hw_reset (it's just c/p for now so nothing changes except calling order -I tested it with various cards and it's ok-) * Further cleanups: ofdm_timings belongs to phy.c rate_duration belongs to pcu.c clock functions are general and belong to reset.c (more to follow) * Reorder functions for better organization: We start with helpers and other functions follow in categories, init functions are last Signed-off-by: Nick Kossifidis <mickflemm@gmail.com> Signed-off-by: John W.

2010-11-22ath5k: Use static constJoe Perches
Using static const generally increases object text and decreases data size.

2010-06-02ath5k: print error message if ANI levels are out of rangeBruno Randolf

2010-04-07ath5k: Adaptive Noise Immunity (ANI) ImplementationBruno Randolf
This is an Adaptive Noise Imunity (ANI) implementation for ath5k. I have looked at both ath9k and HAL sources (they are nearly the same), and even though i have implemented some things differently, the basic algorithm is practically the same, for now. I hope that this can serve as a clean start to improve the algorithm later. This also adds a possibility to manually control ANI settings, right now only thru a debugfs file: * set lowest sensitivity (=highest noise immunity): echo sens-low > /sys/kernel/debug/ath5k/phy0/ani * set highest sensitivity (=lowest noise immunity): echo sens-high > /sys/kernel/debug/ath5k/phy0/ani * automatically control immunity (default): echo ani-on > /sys/kernel/debug/ath5k/phy0/ani * to see the parameters in use and watch them change: cat /sys/kernel/debug/ath5k/phy0/ani Manually setting sensitivity will turn the automatic control off. You can also control each of the five immunity parameters (noise immunity, spur immunity, firstep, ofdm weak signal detection, cck weak signal detection) manually thru the debugfs file. This is tested on AR5414 and nearly doubles the thruput in a noisy 2GHz band. Signed-off-by: Bruno Randolf <br1@einfach.org> Signed-off-by: John W. Linville <linville@tuxdriver.com>
