Subject: [PATCH 2/2] mac80211: minstrel try all rates
Date: Mon, 23 Nov 2009 16:57:18 -0800	[thread overview]
Message-ID: <4B0B2F6E.7050907@irobot.com> (raw)
In-Reply-To: <1259018866.7094.189.camel@johannes.local>

In Ad-Hoc mode, it is possible for minstrel to be initialized without 
complete rate information.  In these cases, throughput suffers because 
not all rates are tried.  This patch tells minstrel to try all rates.  
This won't cause problems, because unsupported rates will simply fail, 
causing minstrel to set their probability to 0%.
