"To configure the device, we use the first I/O region of the PCI
device."

Meh, it does sound a little like we are specifying that it's an PCI I/O
bar.

Let's resurrect the PCI-v2 idea, which is ready to implement now, and a
nice cleanup?  Detach it from the change-of-ring-format idea which is
turning out to be a tarpit.

Thanks,
Rusty.
