If there is a desire for that, I could add it. I found it a bit distracting when I prototyped it. OTOH, it might be useful for -c at least. One of the things I think is helpful in this view is that you can easily see the PCI bridge that is the upstream port of a PCI-e link connecting to a leaf device. -- John Baldwinhome | help
