[PATCH] USB: usbnet (8/9) module for RNDIS devices

This adds host-side RNDIS support to the "usbnet" driver, so Linux can talk
to various devices (often based on WinCE) that otherwise only Windows could
talk to.

Tested with little-endian Linux talking to a Linux-USB Ethernet/RNDIS based
peripheral.  This also includes updates from Eddie C. Dost <ecd@brainaid.de>
for big-endian SPARC Linux talking to a Nokia 9500 Communicator.

It's still marked as EXPERIMENTAL because this code is so young.  This
ought to let Linux to work with various cable modems that previously
would have been "Windows Only".
