From 69d3b6f491545d326135a1def4e290cd577c9a36 Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Wed, 5 Mar 2008 10:58:40 +0100 Subject: [PATCH] mac80211: fix hardware scan completion The mac80211 MLME requires restarting timers after a scan completes but this wasn't done when hardware scan offload was added, so add it now.
