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 |
