That's the point of this ioctl(): so that you don't have to trawl the
registry to find this info.  Sometimes it's inevitable, but if all you
need is the interface specs, this is an easy way to get it.  

On the other hand, your capture engine might already need to grovel
about in the registry, so you'd have this info at hand anyway.
