230718bd 22/* This driver supports wwan (3G/LTE/?) devices using a vendor
423ce8ca
BM		 23 * specific management protocol called Qualcomm MSM Interface (QMI) -
24 * in addition to the more common AT commands over serial interface
25 * management
26 *
27 * QMI is wrapped in CDC, using CDC encapsulated commands on the
28 * control ("master") interface of a two-interface CDC Union
29 * resembling standard CDC ECM. The devices do not use the control
30 * interface for any other CDC messages. Most likely because the
31 * management protocol is used in place of the standard CDC
32 * notifications NOTIFY_NETWORK_CONNECTION and NOTIFY_SPEED_CHANGE
33 *
230718bd
BM		 34 * Alternatively, control and data functions can be combined in a
35 * single USB interface.
36 *
423ce8ca 37 * Handling a protocol like QMI is out of the scope for any driver.
230718bd
BM		 38 * It is exported as a character device using the cdc-wdm driver as
39 * a subdriver, enabling userspace applications ("modem managers") to
40 * handle it.
423ce8ca
BM		 41 *
42 * These devices may alternatively/additionally be configured using AT
230718bd 43 * commands on a serial interface
