+User callback APIs
+~~~~~~~~~~~~~~~~~~
+The add API configures a callback function to be called for each burst of crypto
+ops received on a given crypto device queue pair. The return value is a pointer
+that can be used later to remove the callback using rte_cryptodev_remove_enq_callback().
+Multiple callback functions can be added for a given queue pair.
