There are no hardware requirements as far as i understand it. If your
hardware only has one RX queue and one TX queue, define it as
1. Having more allows you to spread the load over multiple CPUs, with
each queue typically having its own interrupt, and interrupts are then
mapped to a single CPU. But if you don't have any of that, it should
not be a hindrance.
