From 0b2b35f68140ceeb1b78ef85680198e63ebc8649 Mon Sep 17 00:00:00 2001 From: Sean Hefty Date: Thu, 1 Sep 2005 09:28:03 -0700 Subject: [PATCH] IB: Add user-supplied context to userspace CM ABI - Add user specified context to all uCM events. Users will not retrieve any events associated with the context after destroying the corresponding cm_id. - Provide the ib_cm_init_qp_attr() call to userspace clients of the CM. This call may be used to set QP attributes properly before modifying the QP. - Fixes some error handling synchonization and cleanup issues. - Performs some minor code cleanup.
