[V2,RESEND,0/4] Packed virtqueue state support for vDPA

Message

Hi:

This series implements the packed virtqueue state support for
vDPA. This is done via extending the vdpa_vq_state to support packed
virtqueue.

For virtio-vDPA, an initial state required by the virtio spec is set.

For vhost-vDPA, the packed virtqueue support still needs to be done at
both vhost core and vhost-vDPA in the future.

Please review.

Tested with packed=on/off via virtio_vdpa driver.

Change since V1:
- unbreak mlx5_vdpa build

Thanks

  vdpa: support packed virtqueue for set/get_vq_state()
  virtio-pci library: introduce vp_modern_get_driver_features()
  vp_vdpa: allow set vq state to initial state after reset
