[PATCH] virtio-vdpa: add VIRTIO_F_NOTIFICATION_DATA feature support
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 the vqn, next_off and next_wrap for packed virtqueues.
This patch follows a patch [1] by Viktor

[PATCH v2] virtio-vdpa: add VIRTIO_F_NOTIFICATION_DATA feature support
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

Yes, vDPA drivers without kick_vq_with_data should not offer VIRTIO_F_NOTIFICATION_DATA in the first place.
We can be more forgiving in such cases and clear the feature bit + print a warning.
It may be easier to debug when creating a new vDPA driver.
