While we do rte_event_enqueue_burst(), we do not have a way to identify whether
The event is for crypto adapter or the eth adaptor.
At the application layer, we know where to send the event, but in the event lib
We do not know which port it need to be sent.
IMO, event port is specifically designed to work for OP_NEW mode.
I did not find a way to make it land into crypto adapter.
Please let me know in case there is a better option other than adding a new API.
