I wonder what's the value of keeping the default device that is out of the
control of management API.

I think we can remove it like how I did in the v1 version. And actual vendor drivers like mlx5_vdpa will likely should do only user created devices.
I added only for backward compatibility purpose, but we can remove the default simulated vdpa net device.
What do you recommend?
