[v2,0/3] Introduce new class for vDPA device drivers

  As discussed and as described in RFC "[RFC] net: new vdpa PMD for Mellanox devices", new vDPA driver is going to be added for Mellanox devices - vDPA mlx5 and more.

The only vDPA driver now is the IFC driver that is located in net directory.

The IFC driver and the new vDPA mlx5 driver provide the vDPA ops introduced in librte_vhost and not the eth-dev ops.
All the others drivers in net class provide the eth-dev ops.
The set of features is also different.

Create a new class for vDPA drivers and move IFC to this class.
Later, all the new drivers that implement the vDPA ops will be added to the vDPA class.

Also, a vDPA device driver features list was added to vDPA documentation.

Please review the features list and the series.

Later on, I'm going to send the vDPA mlx5 driver.

Thanks.

v2:
Apply comments from Maxime Coquelin, Andrew Rybchenko and Tiwei Bie.

I've fixed few minor things as discussed in this thread.

Summary of other discussions:
- Rosen said he "is not blocking the integration of this patch".
- ifc features need to be filled in a separate patch.
- ifc patches will be merged in the next-virtio tree starting now.
- Andrew and Tiwei asked for some changes in the doc which are addressed in v2,
or justified (features description is chosen to be kept simple for now).

This is the very first step for this new drivers directory,
and we will surely apply some improvements in this area
when adding more drivers.

Applied, thanks
