I see.

How would you feel about changing the nd field of qdev for a void * one,
call it private, or whatever?

then we could have a generic qdev_set_private(dev, p), that does it for
everybody. I must say I kinda dislike that specific dependency on nd for
net devices. Ideally, all devices should be treated as the same.
