This patch (in Linus' tree) apparently didn't make it to 2.6.32. commit 450aae3d7b60a970f266349a837dfb30a539198b Author: Sujith Date: Mon Nov 2 12:33:23 2009 +0530 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. Linville Sujith
