I have to say, I'm not so sure this is actually the same thing.  This
linked documentation shows how to use DPDK on top of the netsvc device,
using uio_hv_generic.

What you are talking about is using DPDK on the Mellanox card, which is
documented here:
https://doc.dpdk.org/guides/nics/mlx4.html
https://docs.microsoft.com/en-us/azure/virtual-network/setup-dpdk

This requires the following modules:
- mlx4_ib
- ib_uverbs

Bastian
