It would be better if a need of this change is explained in the 
description of the patch and I believe the change will be accepted for 
19.08 release and not 19.05.

Hi,

The reason of this change is for a more formal API for cryptodev. Since the
key is for creating session and not meant to be modified by the driver.

The patch is finished I am doing some last checks. Is there any reason to
delay the patch for 19.08?

Regards,
Fan
