27  * Adaptive Noise Immunity (ANI) controls five noise immunity parameters
33  *   - "noise immunity"
35  *   - "spur immunity"
44  * raise or lower immunity accordingly by setting one or more of these
50  * threshold of errors has been reached we will raise immunity.
51  * Also we regularly check the amount of errors and lower or raise immunity as
61  * ath5k_ani_set_noise_immunity_level() - Set noise immunity level

117 		ATH5K_ERR(ah, "spur immunity level %d out of range",  in ath5k_ani_set_spur_immunity_level()
213  * ath5k_ani_raise_immunity() - Increase noise immunity
219  * Try to raise noise immunity (=decrease sensitivity) in several steps
