From a0af5f14542a2e0687f95e093a33ea7301fe8cc5 Mon Sep 17 00:00:00 2001 From: Helmut Schaa Date: Fri, 9 Nov 2007 16:25:08 +0100 Subject: [PATCH] mac80211: Fix queuing of scan containing a SSID This patch fixes scanning for specific ssid's which is broken due to the scan being queued up without respecting the ssid to scan for.
