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() Signed-off-by: Abhinandan Gujjar <redacted> Signed-off-by: Nikhil Rao <redacted> --- lib/librte_security/rte_security.h | 29 +++++++++++++++++++++++++++++ 1 file changed, 29 insertions(+)
