 23 /* This driver supports wwan (3G/LTE/?) devices using a vendor
 24  * specific management protocol called Qualcomm MSM Interface (QMI) -
 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
