[PATCH] USB: usbnet (7/9) module for CDC Ethernet
Makes the CDC Ethernet support live in a separate driver module.
This module is a bit special since it exports utility functions
that are reused by the the Zaurus and RNDIS drivers, but it's
not "core" like usbnet itself.

- The Linux-USB CDC Ethernet Gadget driver is an open implementation.
- This driver should work with at least the following devices:

- * Broadcom Cable Modem (reference design)
- * Toshiba PCX1100U

- name is used instead.
