Subject: [dpdk-dev] [RFC 21/24] examples/vhost_scsi: add virtio-vhost-user support
Date: Fri, 19 Jan 2018 13:44:41 +0000	[thread overview]
Message-ID: <20180119134444.24927-22-stefanha@redhat.com> (raw)
In-Reply-To: <20180119134444.24927-1-stefanha@redhat.com>

The new --virtio-vhost-user-pci command-line argument uses
virtio-vhost-user instead of the default AF_UNIX transport.
