Does that mean application will not call the cryptodev_enqueue_burst and corresponding dequeue burst.
It would be a new API something like process_packets and it will have the crypto processed packets while returning from the API?

I still do not understand why we cannot do with the conventional crypto lib only.
As far as I can understand, you are not doing any protocol processing or any value add
To the crypto processing. IMO, you just need a synchronous crypto processing API which
Can be defined in cryptodev, you don't need to re-create a crypto session in the name of
Security session in the driver just to do a synchronous processing.
