The trick isn't the classification part, but needing multiple hardware queues. If you have multiple hardware queues, it doesn't matter

Providers use sacrifical physical interfaces, e.g. a T1, because some routers aren't very good at managing multiple queues on a single physical
interface, and may not have multiple hardware queues on a single physical
