Subject: [PATCH opensm] Setup SM port GUID in subnet object as soon as it is known
Date: Thu, 04 Apr 2013 07:10:23 -0400	[thread overview]
Message-ID: <515D5F9F.5080301@dev.mellanox.co.il> (raw)


rather than wait for local NodeInfo response
This allows plugin to know SM port GUID at construct() time
