This patch introduce a vDPA driver for virtio-pci device. It bridges
the virtio-pci control command to the vDPA bus. This will be used for
features prototyping and testing.

Note that get/restore virtqueue state is not supported which needs
extension on the virtio specification.

Without 'that' maybe sound better, but I'm not a native speaker :-)

Yes, drop 'that', please.

Will fix.

Thanks
