[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).
