Subject: [net-next][PATCH v3 09/13] RDS: IB: handle the RDMA CM time wait event
Date: Tue,  1 Mar 2016 15:20:50 -0800	[thread overview]
Message-ID: <1456874454-10355-10-git-send-email-santosh.shilimkar@oracle.com> (raw)
In-Reply-To: <1456874454-10355-1-git-send-email-santosh.shilimkar@oracle.com>

Drop the RDS connection on RDMA_CM_EVENT_TIMEWAIT_EXIT so that
it can reconnect and resume.

While testing fastreg, this error happened in couple of tests but
was getting un-noticed.
