Because currently device_api definitions are not central to mdev_core. It should be in mdev core and not in include/uapi/linux/vfio.h.
So, it needs to refactored.
Additionally, current mlx5 mdev are not going to be bound to vfio framework.
So, it is not breaking anything.
+ class_id is getting implemented to have more appropriate binding method.
Hence it is not implemented.

Yes.

Local to this system.
