[PATCH] USB: usbnet (2/9) module for simple network links 

This patch creates the first of several separate "minidriver" modules
for "usbnet".  This one handles only the very simplest hardware, which
can be handled almost entirely by the "usbnet" core.

    - Move device-specific bits into new "cdc_subset.c" driver,
      shrinking "usbnet" by a bunch;

    - Export the functions needed to support this minidriver
      (with EXPORT_SYMBOL_GPL);

    - Update Kconfig and kbuild accordingly.

This one handles about a dozen different device types, with the most
notable ones being Gumstix and most Linux-based PDAs (except Zaurus
running that ancient code from Sharp).

Note that while many USB host-to-host cables can work in this mode,

commonly not being able to handle certain events (like replugging
the host on the other end) very well. Also, these devices will

/*
* 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.
