After a quick glance into the datasheet, I understand that the current version of hardware supports reading TIM, TSF and some more bits related to DTIM from a beacon. As far as this patch is concerned, since ath9k can use mac80211 for sending a null data frame, it is quite redundant to enable the TIM interrupt as it can be parsed in mac80211 itself.
