/**
* ath5k_hw_check_beacon_timers - Check if the beacon timers are correct
*
* @ah: The &struct ath5k_hw
* @intval: beacon interval
*
* This is a workaround for IBSS mode:
*
* The need for this function arises from the fact that we have 4 separate
* HW timer registers (TIMER0 - TIMER3), which are closely related to the
* next beacon target time (NBTT), and that the HW updates these timers
* seperately based on the current TSF value. The hardware increments each
* timer by the beacon interval, when the local TSF coverted to TU is equal
* to the value stored in the timer.
*
* The reception of a beacon with the same BSSID can update the local HW TSF
* at any time - this is something we can't avoid. If the TSF jumps to a
* time which is later than the time stored in a timer, this timer will not
* be updated until the TSF in TU wraps around at 16 bit (the size of the
* timers) and reaches the time which is stored in the timer.
*
* The problem is that these timers are closely related to TIMER0 (NBTT) and
* that they define a time "window". When the TSF jumps between two timers
* (e.g. ATIM and NBTT), the one in the past will be left behind (not
* updated), while the one in the future will be updated every beacon
* interval. This causes the window to get larger, until the TSF wraps
* around as described above and the timer which was left behind gets
* updated again. But - because the beacon interval is usually not an exact
* divisor of the size of the timers (16 bit), an unwanted "window" between
* these timers has developed!
*
* This is especially important with the ATIM window, because during
* the ATIM window only ATIM frames and no data frames are allowed to be
* sent, which creates transmission pauses after each beacon. This symptom
* has been described as "ramping ping" because ping times increase linearly
* for some time and then drop down again. A wrong window on the DMA beacon
* timer has the same effect, so we check for these two conditions.
*
* Returns true if O.K.
