Subject: [PATCH] opensm: configure multicast only once during sweep
Date: Thu, 6 Jan 2011 18:39:05 +0200	[thread overview]
Message-ID: <4D25F029.1080005@gmail.com> (raw)

[PATCH] configure multicast only once during sweep

opensm performed multicast configuration twice during sweep by calling
two different function that are very similar.
remove osm_mcast_mgr_process() which had a bug and didn't clear mlid bit
after configuration and rename osm_mcast_mgr_process_mgroups()
to osm_mcast_mgr_process()
