There is 'ath_ani_calibrate' which basically does three things (apart from timer management boilerplate): -- calls ath9k_hw_calibrate to perform 'long calibration' -- calls ath9k_hw_calibrate to perform 'short calibration' -- calls ath9k_hw_ani_monitor to get ANI statistics (?) So there seem to be three major parts of ANI: long calibration, short calibration, and third thing which I find hard to name correctly so I'll refer to it as 'ANI-ANI'. From your response I understand that 'short calibration' and 'long calibration' generally considered to be part of think called ANI. Considering this name 'disable_ani' in a sense that it disables 'ath_ani_calibrate' as a whole looks ok. But config.enable_ani is used to control if 'ANI-ANI' gets executed (and this was somewhat true before my patch). So, having two variables which 'negated' names is confusing by itself, i.e. enable_ani vs disable_ani. But more confusing is the fact that they actually control different things and have different meaning, so disable_ani != (!enable_ani). I do understand that my 'ANI-ANI' probably has proper name and I think that 'enable_ani' should probably be renamed using this proper name. I'd really appreciate if you could let me know where my understanding is incorrect. Thanks! -- Truthfully yours, Martynov Nikolay.
