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
