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