From mboxrd@z Thu Jan 1 00:00:00 1970 From: Hal Rosenstock Subject: [PATCH opensm] osm_ucast_mgr.c: Support diverse paths for LMC > 0 when scatter_ports is enabled Date: Wed, 11 Feb 2015 07:22:21 -0500 Message-ID: <54DB497D.70600@dev.mellanox.co.il> Mime-Version: 1.0 Content-Type: text/plain; charset=ISO-8859-1 Content-Transfer-Encoding: 7bit Return-path: Sender: linux-rdma-owner-u79uwXL29TY76Z2rM5mHXA@public.gmane.org To: "linux-rdma (linux-rdma-u79uwXL29TY76Z2rM5mHXA@public.gmane.org)" Cc: Vladimir Koushnir , Shlomi Nimrodi List-Id: linux-rdma@vger.kernel.org From: Vladimir Koushnir The patch adds an ability to calculate diverse paths for all LIDs (LMC > 0) derived from the same Base LID, when scatter ports is enabled (different from 0). We apply randomization during selection of the outports only when routing is calculated for the Base LID. For LIDs different from the Base LID, we don't randomize the outport but apply the procedure for calculating diverse path as if scatter_ports equals 0. The patch is relevant for minhop/updn routing.
