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

66 * hits, some packets will still arrive with an intact header.
