I don't think ath9k has ever been tested with longer sleep durations based on dtim period. We have always programmed the hardware to wake up for every beacon interval, using the TIM_TIMER interrupt. And since the TIM bit needs to be checked for every beacon, the sleep duration has to be the beacon interval. Also, the bmiss threshold needs to be adjusted based on the sleep duration. We are hardcoding it currently in the driver using ATH_DEFAULT_BMISS_LIMIT. This will break, too. Using dtim for PS needs more testing before it can be used, so we can have the original behavior for now.
