From 450aae3d7b60a970f266349a837dfb30a539198b Mon Sep 17 00:00:00 2001 From: Sujith Date: Mon, 2 Nov 2009 12:33:23 +0530 Subject: [PATCH] mac80211: Fix IBSS merge Currently, in IBSS mode, a single creator would go into a loop trying to merge/scan. This happens because the IBSS timer is rearmed on finishing a scan and the subsequent timer invocation requests another scan immediately. This patch fixes this issue by checking if we have just completed a scan run trying to merge with other IBSS networks. Signed-off-by: Sujith Signed-off-by: John W.
