From e515e9cb6477dbd039a49c38794d8b91491339a2 Mon Sep 17 00:00:00 2001 From: Zefir Kurtisi Date: Fri, 9 May 2014 15:19:42 +0200 Subject: [PATCH] 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 Signed-off-by: John W.
