Subject: [PATCH for-next 18/20] IB/hns: Update the rq head when modify qp state
Date: Fri, 9 Sep 2016 18:30:49 +0800	[thread overview]
Message-ID: <1473417051-99560-19-git-send-email-salil.mehta@huawei.com> (raw)
In-Reply-To: <1473417051-99560-1-git-send-email-salil.mehta-hv44wF8Li93QT0dZR+AlfA@public.gmane.org>

From: Lijun Ou <oulijun-hv44wF8Li93QT0dZR+AlfA@public.gmane.org>

The rq head in qpc was zero will miss the rq wqes which
have be sent, so here we should take the real value.
