>Description:
When the chip is reset, the beacon programming in STA Mode needs to be re-done, else none of the registers will be programmed and thus no beacon miss events are generated.

This has shown up when I add a hardware reset to ath_bmiss_proc(). After that ath_reset() call is finished, the beacon timers aren't re-programmed.

So, I need to review the beacon miss handling and ath_reset() path; check whether the beacon timers are being reprogrammed or not.
