If you're able to detect the line card type when plugging it in, I don't
understand why you need system administrator to pre-provision it using
such an interface? Wouldn't it make more sense to simply detect the
case? Or is it that you expect these things to be moved around and want
to make sure that you can configure the associated netdevices before the
card is plugged in?
