+ * This supports simple USB network links that don't require any special
+ * framing or hardware control operations.  The protocol used here is a
+ * strict subset of CDC Ethernet, with three basic differences reflecting
+ * the goal that almost any hardware should run it:
+ *
+ *  - Minimal runtime control:  one interface, no altsettings, and
+ *    no vendor or class specific control requests.  If a device is
+ *    configured, it is allowed to exchange packets with the host.
+ *    Fancier models would mean not working on some hardware.
+ *
+ *  - Minimal manufacturing control:  no IEEE "Organizationally
+ *    Unique ID" required, or an EEPROMs to store one.  Each host uses
+ *    one random "locally assigned" Ethernet address instead, which can
+ *    of course be overridden using standard tools like "ifconfig".
+ *    (With 2^46 such addresses, same-net collisions are quite rare.)
+ *
+ *  - There is no additional framing data for USB.  Packets are written
+ *    exactly as in CDC Ethernet, starting with an Ethernet header and
+ *    terminated by a short packet.  However, the host will never send a
+ *    zero length packet; some systems can't handle those robustly.
+ *
+ * Anything that can transmit and receive USB bulk packets can implement
+ * this protocol.  That includes both smart peripherals and quite a lot
+ * of "host-to-host" USB cables (which embed two devices back-to-back).
+ *
+ * Note that although Linux may use many of those host-to-host links
+ * with this "cdc_subset" framing, that doesn't mean there may not be a
+ * better approach.  Handling the "other end unplugs/replugs" scenario
+ * well tends to require chip-specific vendor requests.  Also, Windows
+ * peers at the other end of host-to-host cables may expect their own
+ * framing to be used rather than this "cdc_subset" model.
