Currently in ath9k code there is an attempt which is meant to disable ANI for ar9100 and ar9340. But it doesn't really achieve this. All it does is disable ANI init and setup (i.e. calls to ath9k_hw_ani_setup and ath9k_hw_ani_init). Since ath9k_hw_ani_setup is not called ah->config.ani_poll_interval is never initialized (i.e. it is always zero) and ath_ani_calibrate always executes ANI procedures (over uninitialized ANI parameters). Moreover, ath_ani_calibrate is being called each 1ms because common->ani.timer is set to zero interval because ah->config.ani_poll_interval==0 (and thus smallest value of all intervals). Normally it should not be called this often. This patch changes the code so config.enable_ani is used to check if ANI should be performed. Also, this pacthset enables ANI for ar9100 - ANI was always performed for this chip, but this patch fixes the fact that it was performed over uninitialized data. All comments and suggestions are appreciated. Thanks.
