230718bd 23/* This driver supports wwan (3G/LTE/?) devices using a vendor
423ce8ca
BM		 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 *
230718bd
BM		 35 * Alternatively, control and data functions can be combined in a
36 * single USB interface.
37 *
423ce8ca 38 * Handling a protocol like QMI is out of the scope for any driver.
230718bd
BM		 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.
423ce8ca
BM		 42 *
43 * These devices may alternatively/additionally be configured using AT
230718bd 44 * commands on a serial interface

61 * A firmware bug common among several devices cause them to send raw
62 * IP packets under some circumstances. There is no way for the
63 * driver/host to know when this will happen. And even when the bug
64 * hits, some packets will still arrive with an intact header.
65 *
66 * The supported devices are only capably of sending IPv4, IPv6 and
67 * ARP packets on a point-to-point link. Any packet with an ethernet
68 * header will have either our address or a broadcast/multicast
69 * address as destination. ARP packets will always have a header.
