From d43c7b37ad787173d08683f05eadeea0398fefdf Mon Sep 17 00:00:00 2001 From: Vladimir Koutny Date: Mon, 31 Mar 2008 17:05:03 +0200 Subject: [PATCH] mac80211: correct use_short_preamble handling ERP IE bit for preamble mode is 0 for short and 1 for long, not the other way around. This fixes the value reported to the driver via bss_conf->use_short_preamble field. Signed-off-by: Vladimir Koutny Signed-off-by: John W.
