[dpdk-dev,RFC,v3,3/3] security: add support to set session private data
Checks
Commit Message
The application may want to store private data along with the
rte_security that is transparent to the rte_security layer.
For e.g., If an eventdev based application is submitting a
rte_security_session operation and wants to indicate event information
required to construct a new event that will be enqueued to eventdev
after completion of the rte_security operation. This patch provides a
mechanism for the application to associate this information with the
rte_security session. The application can set the private data using
rte_security_session_set_private_data() and retrieve it using
rte_security_session_get_private_data()
