As far as I can tell there is no reason for a multi-port device to be represented through verbs as a single device with multiple protocols. If you have a single physical chip with two ports and they are running different protocols it seems much cleaner to me to report it to verbs apps as two devices. Doing this avoids creating compatability problems.
