  * struct iwl_trans_ops - transport specific operations
  * @start_hw: starts the HW- from that point on, the HW can send interrupts
+ * @stop_hw: stops the HW- from that point on, the HW will be in low power but

  * @start_device: allocates and inits all the resources for the transport
  *                layer.
  * @fw_alive: called when the fw sends alive notification
