/* 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

 * hits, some packets will still arrive with an intact header.
 *
 * The supported devices are only capably of sending IPv4, IPv6 and

 * header will have either our address or a broadcast/multicast
