26 /* This driver supports wwan (3G/LTE/?) devices using a vendor
27 * specific management protocol called Qualcomm MSM Interface (QMI) -
28 * in addition to the more common AT commands over serial interface
31 * QMI is wrapped in CDC, using CDC encapsulated commands on the
32 * control ("master") interface of a two-interface CDC Union
33 * resembling standard CDC ECM. The devices do not use the control
34 * interface for any other CDC messages. Most likely because the
35 * management protocol is used in place of the standard CDC
36 * notifications NOTIFY_NETWORK_CONNECTION and NOTIFY_SPEED_CHANGE
38 * Alternatively, control and data functions can be combined in a
39 * single USB interface.
41 * Handling a protocol like QMI is out of the scope for any driver.
42 * It is exported as a character device using the cdc-wdm driver as
43 * a subdriver, enabling userspace applications ("modem managers") to
46 * These devices may alternatively/additionally be configured using AT
47 * commands on a serial interface
