From f93439e476d012b2503dbb07fe0fc675bcbff099 Mon Sep 17 00:00:00 2001 From: Devesh Sharma Date: Mon, 9 Jun 2014 10:52:38 +0530 Subject: [PATCH] RDMA/ocrdma: Do not skip setting deferred_arm When ib_request_notify_cq() is called for the first time, ocrdma tries to skip setting deffered_arm flag. This may lead CQ to an un-armed state thus never generating a CQ event and leaving consumer hung. This patch removes the part of code that skips setting deferred_arm.
