Microsoft Windows XP bundles the "Remote NDIS" (RNDIS) protocol,
and Microsoft provides redistributable binary RNDIS drivers for
older versions of Windows.

If you say "y" here, the Ethernet gadget driver will try to provide
a second device configuration, supporting RNDIS to talk to such
Microsoft USB hosts.

To make MS-Windows work with this, use Documentation/usb/linux.inf
as the "driver info file". For versions of MS-Windows older than
XP, you'll need to download drivers from Microsoft's website; a URL
is given in comments found in that info file.
