Yes, "dpdk" plus a number is a physical interface.

Those are DPDK vhost-user ports. Those ports use shared mem with a
notification mechanism to exchange packets with qemu. However, you
need to configure qemu/VM to actually use them.
Something like:
<interface type='vhostuser'>
<mac address='52:54:00:24:1b:c4'/>
<source type='unix' path='/var/run/openvswitch/vhost0' mode='client'/>
<model type='virtio'/>
<address type='pci' domain='0x0000' bus='0x00' slot='0x02'
function='0x0'/>
</interface>

Sorry, I didn't understand.
