- * @cur_req_prepared: current request is prepared
- * @list: link with the global crypto engine list

- * @queue: the crypto queue of the engine
- * @rt: whether this queue is set to run as a realtime task
- * @prepare_crypt_hardware: a request will soon arrive from the queue
- * so the subsystem requests the driver to prepare the hardware
- * by issuing this call
- * @unprepare_crypt_hardware: there are currently no more requests on the
- * queue so the subsystem notifies the driver that it may relax the
- * hardware by issuing this call
- * @prepare_request: do some prepare if need before handle the current request
- * @unprepare_request: undo any work done by prepare_message()
- * @crypt_one_request: do encryption for current request
- * @kworker: thread struct for request pump
- * @kworker_task: pointer to task for request pump kworker thread
- * @pump_requests: work struct for scheduling work to the request pump
- * @priv_data: the engine private data
- * @cur_req: the current request which is on processing
