If a driver wants to use the new Output Queue poll code, then the qdio layer must disable its internal Queue scanning. Let the driver select this mode by passing a special scan_threshold of 0. As the scan_threshold is the same for all Output Queues, also move it into the main qdio_irq struct. This allows for fast opt-out checking, a driver is expected to operate either _all_ or none of its Output Queues in polling mode.
