ath9k: non-functional: calculate DFS pulse interval per-wiphy
Systems with multiple DFS channel detectors need to track timestamp of previous pulse per instance to display the correct pulse interval. Since the interval value is used for debug printing only, this is a non-functional modification. Signed-off-by: Zefir Kurtisi <zefir.kurtisi@neratec.com> Signed-off-by: John W.
