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