Please be explicit about "vhost-pci" vs "vhost-pci-net" in future
emails.  In this email you use "vhost-pci" to mean both things and it's
likely to cause confusion.  For example, MQ and DPDK PMD are related to
vhost-pci-net.

This is a general problem with all of vhost-user, not just vhost-pci.
People sometimes focus solely on virtio-net.  It causes layering
violations and protocol limitations because they are not thinking about
the virtio device model as a whole.

Eventually virtio-gpu, virtio-scsi, etc should all work over vhost-pci
so it's important to keep the virtio architecture in mind with a
separation between the transport and devices.
