From 38ca83a588662f0af684ba2567dd910a564268ab Mon Sep 17 00:00:00 2001 From: Amir Vadai Date: Tue, 22 Jul 2008 14:14:23 -0700 Subject: [PATCH] RDMA/cma: Add RDMA_CM_EVENT_TIMEWAIT_EXIT event Consumers that want to re-use their QPs in new connections need to know when the QP has exited the timewait state. Report the timewait event through the rdma_cm.
