Subject: [PATCH 2/8] librdmacm: Use SRQ in rdma_create_qp
Date: Tue,  1 Jul 2014 23:11:13 -0700	[thread overview]
Message-ID: <1404281479-6755-3-git-send-email-sean.hefty@intel.com> (raw)
In-Reply-To: <1404281479-6755-1-git-send-email-sean.hefty-ral2JQCrhuEAvxtiuMwx3w@public.gmane.org>

From: Sean Hefty <sean.hefty-ral2JQCrhuEAvxtiuMwx3w@public.gmane.org>

If an application has allocated an SRQ on an rdma_cm_id, use
it when creating a QP.
