Nak, it should fail. If sufficient queues are not available how would the pipeline work?

	/*
	 * The pipelines are setup in the following manner:
	 *
	 * eth_dev_count = 2, nb_stages = 2.
	 *
	 *	queues = 6
	 *	stride = 3
	 *
	 *	event queue pipelines:
	 *	eth0 -> q0 -> q1 -> (q2->tx)
	 *	eth1 -> q3 -> q4 -> (q5->tx)
	 *
	 *	q2, q5 configured as ATOMIC | SINGLE_LINK
	 *
	 */
