Subject: [PATCH 1/2] mac80211: copy peer MCS TX parameters
Date: Fri, 25 Feb 2011 12:24:10 +0100 [thread overview]
Message-ID: <20110225112620.262596927@sipsolutions.net> (raw)
In-Reply-To: 20110225112409.977212647@sipsolutions.net
From: Johannes Berg <johannes.berg@intel.com>
We need to copy this to allow drivers to look
at the information where needed.
