From 4f267c1198cf57fc9fc444c78649bca018cc63af Mon Sep 17 00:00:00 2001 From: Janusz Dziedzic Date: Wed, 9 Apr 2014 13:47:12 +0200 Subject: [PATCH] cfg80211: reg: set DFS CAC time in case of custom regd Set DFS CAC time also in case of using custom and strict regulatory from drivers. In other case we could have unset DFS CAC time directly after driver loaded and before issue regulatory set from user mode.
