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)
