* The *dequeue* operation gets one or more events from the event ports.
* The application process the events and send to downstream event queue through
* rte_event_enqueue_burst() if it is an intermediate stage of event processing,
- * on the final stage, the application may send to different subsystem like
- * ethdev to send the packet/event on the wire using ethdev
- * rte_eth_tx_burst() API.
+ * on the final stage, the application may use Tx adapter API for maintaining
+ * the ingress order and then send the packet/event on the wire.
*
* The point at which events are scheduled to ports depends on the device.
* For hardware devices, scheduling occurs asynchronously without any software
