- * the waiter stays blocked. If no function is given, any
- * of the listed commands will unblock the waiter.
- * @cmds: command IDs

- * @triggered: waiter should be woken up
- * @aborted: wait was aborted
- *
- * This structure is not used directly, to wait for a

- * parameters. Then do whatever will cause the ucode
- * to notify the driver, and to wait for that then
- * call iwlagn_wait_notification().

- * Each notification is one-shot. If at some point we
- * need to support multi-shot notifications (which
