Yes, the driver now creates per-cpu IRQs for completions. However if
you don't trigger any completion events then you won't get any
interrupts. That's different from the workqueues, which are used to
poll the hardware for port changes and internal errors (and which are
single-threaded and can be put on whatever "system services" CPU you want)
