Subject: [dpdk-dev] [PATCH 25/28] examples/vhost_scsi: add virtio-vhost-user support
Date: Wed, 19 Jun 2019 18:14:50 +0300 [thread overview]
Message-ID: <1560957293-17294-26-git-send-email-ndragazis@arrikto.com> (raw)
In-Reply-To: <1560957293-17294-1-git-send-email-ndragazis@arrikto.com>
From: Stefan Hajnoczi <stefanha@redhat.com>
The new --virtio-vhost-user-pci command-line argument uses
virtio-vhost-user instead of the default AF_UNIX transport.
