OK, I don't think the "naming" idea works though. A userspace user would have to open each one in turn to get its name. I'd stick with numbers. You also don't have dynamic creation and removal, except by hotpluging the entire device (which was on your requirements page). I'd put a size and bitmap in the configuration space, and use that to indicate what ports exist. Register on the change interrupt to get updates. Drop the control vq entirely.
