I disagree.  Assuming one can go from the driver private to the netdev

locks us into the current implementation of how the netdev and driver
private memory is allocated.

If you want to style your driver such that the private is passed
around instead of the netdev, put a pointer back to the netdev object
in your private data structure.

I'm surprised you're okay with the memory waste of that, but you bring
up the ability to change the interface later, which is a great point.
I'll submit a patch for that random driver, and I'll also refactor
WireGuard to do the same. Thanks for the guidance.
