[PATCH] virtio-vdpa: add VIRTIO_F_NOTIFICATION_DATA feature support
...IO_F_NOTIFICATION_DATA support for vDPA transport.
If this feature is negotiated, the driver passes extra data when kicking
a virtqueue.
A device that offers this feature needs to implement the
kick_vq_with_data callback.
kick_vq_with_data receives the vDPA device and data.
data includes the vqn, next_off and next_wrap for packed virtqueues.
This patch follows a patch [1] by Viktor Prutyanov which adds support
for the MMIO, channel I/O and modern PCI transports.
This patch needs to be applied on top of Viktor's patch.
