> When an event device is stopped, it drains all event queues and ports.
> These events may contain pointers, so to prevent memory leaks eventdev now
> supports a user-provided flush callback that is called during the queue
> drain process. This callback is stored in process memory, so the callback
> must be registered by any process that may call rte_event_dev_stop().
>
> This commit also clarifies the behavior of rte_event_dev_stop().
