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

62 * A firmware bug common among several devices cause them to send raw
63 * IP packets under some circumstances.  There is no way for the
64 * driver/host to know when this will happen.  And even when the bug
65 * hits, some packets will still arrive with an intact header.
66 *
67 * The supported devices are only capably of sending IPv4, IPv6 and
68 * ARP packets on a point-to-point link. Any packet with an ethernet
69 * header will have either our address or a broadcast/multicast
70 * address as destination.  ARP packets will always have a header.
71 *
72 * This means that this function will reliably add the appropriate
73 * header iff necessary, provided our hardware address does not start
74 * with 4 or 6.
