To program the completion queue context correctly, the control plane must know the scheduling mode not only for the Tx queue, but also for the completion queue. Unfortunately, currently the driver sets the scheduling mode only for the Tx queues. Propagate the scheduling mode data for the completion queue as well when sending the queue configuration messages.
