>=20
> The patch introduces a new PMD. This PMD is implemented as thin wrapper
> of librte_vhost. It means librte_vhost is also needed to compile the PMD.
> The vhost messages will be handled only when a port is started. So start
> a port first, then invoke QEMU.
>=20
> The PMD has 2 parameters.
>  - iface:  The parameter is used to specify a path to connect to a
>            virtio-net device.
>  - queues: The parameter is used to specify the number of the queues
>            virtio-net device has.
>            (Default: 1)

> Here is an example.
> $ ./testpmd -c f -n 4 --vdev 'eth_vhost0,iface=3D/tmp/sock0,queues=3D1' -=
