Subject: [dpdk-dev] [PATCH v13 09/10] net/virtio-user: fail if q used with packed vq
Date: Fri, 14 Dec 2018 16:59:15 +0100 [thread overview]
Message-ID: <20181214155916.1142-10-jfreimann@redhat.com> (raw)
In-Reply-To: <20181214155916.1142-1-jfreimann@redhat.com>
Until we have support for ctrl virtqueues let's disable it and
fail device initalization if specified as a parameter.
