Hi, 

Going back to this merged commit,

> The vdpa sample application creates vhost-user sockets by using the vDPA
> backend. vDPA stands for vhost Data Path Acceleration which utilizes virtio

> acceleration. As vDPA driver can help to set up vhost datapath, this
> application doesn't need to launch dedicated worker threads for vhost
> enqueue/dequeue operations.

It doesn't seems like qemu has the id=vdpa and netdev=vdpa options. 
Grepping vdpa on qemu returns empty. 

Am using QEMU v3.1.0-513-gfb177a0. Commit head is fb177a036f2e ("MAINTAINERS: Mark RISC-V as Supported").

Did I missed anything?
