From 93c75786e8d8e8e245a479209a84b19292d08e7e Mon Sep 17 00:00:00 2001 From: Simon Wunderlich Date: Thu, 11 Jul 2013 20:29:49 +0200 Subject: [PATCH] mac80211: fix off-by-one regression in ibss beacon generation There is an off-by-one error in the beacon generation for the ibss mode, falsely a rate the extended supported rates which was already added to supported rates, messing up the beacon. This was introduced by commit "mac80211: select and adjust bitrates according to channel mode".
