Add VIRTIO_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: 16 bits vqn and 16 bits next available index for split virtqueues. 16 bits vqs, 15 least significant bits of next available index and 1 bit 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.
