Subject: [PATCH] mac80211: Fix mac80211 station info rx bitrate for IBSS mode
Date: Thu, 01 May 2014 10:03:46 +0200 [thread overview]
Message-ID: <4194886.cHRlWHyH6L@desktop.local> (raw)
From: Henning Rogge <hrogge@gmail.com>
Filter out incoming multicast packages before applying their bitrate
to the rx bitrate station info field to prevent them from setting the
rx bitrate to the basic multicast rate.
