    ath: use PRI value given by spec for fixed PRI · 44acedb0
    Peter Oh authored
    PRI value is used as divider when DFS detector analyzes candidate
    radar pulses.
    If PRI deviation is big from its origin PRI, DFS detector could miss
    valid radar reports since HW often misses detecting radar pulses and
    causes long interval value of pulses.
    
    For instance from practical results, if runtime PRI is calculated as
    1431 for fixed PRI value of 1428 and delta timestamp logs 15719,
    the modular remainder will be 1409 and the delta between the remainder
    and runtime PRI is 22 that is bigger than PRI tolerance which is 16.
    As a result this radar report will be ignored even though it's valid.
    
    By using spec defined PRI for fixed PRI, we can correct this error.
