This series enabled Intel FGPA SmartNIC C5000X-PL virtio-blk for vDPA.

Looking at the IFCVF upstream vDPA driver (with this series applied), it 
seems that there is still some cleaning to be done to support virtio-blk 
devices:

- ifcvf_vdpa_get_config() and ifcvf_vdpa_set_config() use
  `sizeof(struct virtio_net_config)` to check the inputs.
  This seems wrong for a virtio-blk device. Maybe we can set the config
  size for each device in ifcvf_vdpa_dev_add() and use that field to
  check the inputs. We can reuse the same field also in
  ifcvf_vdpa_get_config_size().

- Just for make the code more readable we should rename `net_cfg` field
  to `device_cfg`in `struct ifcvf_hw`.

What do you think?

Thanks,
Stefano
