Subject: [dpdk-dev] [PATCH v14 09/10] net/virtio-user: fail if cq used with packed vq
Date: Mon, 17 Dec 2018 22:31:38 +0100	[thread overview]
Message-ID: <20181217213139.19299-10-jfreimann@redhat.com> (raw)
In-Reply-To: <20181217213139.19299-1-jfreimann@redhat.com>

Until we have support for control virtqueues let's disable it and
fail device initalization if specified as a parameter.
