Subject: [PATCH] opensm/mcast_tbl: set max_mlid_ho as actually configured mlid
Date: Thu, 29 Oct 2009 21:19:45 +0200	[thread overview]
Message-ID: <20091029191945.GE20136@me> (raw)
In-Reply-To: <20091029191732.GB20136@me>


Set switch's mcast table max_mlid_ho as actually configured mlid for the
switch instead of a value extended to MFT block size aligned. This makes
mlid handling checks to be more reliable.
