Hello, Thank you for your thorough response. I want to disable the resets of these registers because I sample these register values to create an estimate of when the channel is sensed as being busy for a long periods of time. It would make my data easier to work with. If I were to disable ath5k_hw_ani_get_listen_time(), would it affect the performance of the driver? If so, improving ath5k_hw_ani_get_listen_time() would be more difficult without resetting the values since the registers overflow and we would not know the amount of cycles the TX and RX values would have increased until the overflow point. I think the easiest thing for me to do would be to disable the resets, as long as it does not affect the performance of the driver.
