/* 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

* A firmware bug common among several devices cause them to send raw

* driver/host to know when this will happen. And even when the bug
* hits, some packets will still arrive with an intact header.
*
* The supported devices are only capably of sending IPv4, IPv6 and
* ARP packets on a point-to-point link. Any packet with an ethernet
* header will have either our address or a broadcast/multicast
* address as destination. ARP packets will always have a header.
*
* This means that this function will reliably add the appropriate
* header iff necessary, provided our hardware address does not start
* with 4 or 6.
*
* Another common firmware bug results in all packets being addressed
* to 00:a0:c6:00:00:00 despite the host address being different.
* This function will also fixup such packets.
