It doesn't look like the driver is doing deferred start correctly.
Expect some logic like this from ixgbe to be done from dev_start
handler. There is nothing telling hardware what queues to enable.

	for (i = 0; i < dev->data->nb_tx_queues; i++) {
		txq = dev->data->tx_queues[i];
		if (!txq->tx_deferred_start) {
			ret = ixgbe_dev_tx_queue_start(dev, i);
			if (ret < 0)
				return ret;
		}
	}

	for (i = 0; i < dev->data->nb_rx_queues; i++) {
		rxq = dev->data->rx_queues[i];
		if (!rxq->rx_deferred_start) {
			ret = ixgbe_dev_rx_queue_start(dev, i);
			if (ret < 0)
				return ret;
		}
	}
