  25  * in addition to the more common AT commands over serial interface
  26  * management
  27  *
  28  * QMI is wrapped in CDC, using CDC encapsulated commands on the
  29  * control ("master") interface of a two-interface CDC Union
  30  * resembling standard CDC ECM.  The devices do not use the control
  31  * interface for any other CDC messages.  Most likely because the
  32  * management protocol is used in place of the standard CDC
  33  * notifications NOTIFY_NETWORK_CONNECTION and NOTIFY_SPEED_CHANGE
  34  *
  35  * Alternatively, control and data functions can be combined in a
  36  * single USB interface.
  37  *
  38  * Handling a protocol like QMI is out of the scope for any driver.
  39  * It is exported as a character device using the cdc-wdm driver as
  40  * a subdriver, enabling userspace applications ("modem managers") to
  41  * handle it.
  42  *
  43  * These devices may alternatively/additionally be configured using AT
  44  * commands on a serial interface
