Subject: [PATCH 7/8] Add Wireless Extensions to rndis_host
The bulk of this patch is the addition of a new file that
implements the wireless extensions for RNDIS devices.
The rest are some smaller changes to usbnet and rndis_host
to hook the wireless extensions into them:
* a private data pointer is added to usbnet.
* a callback is added to driver_info to signal link state changes.
* a physical medium type check is added to rndis_bind to check for
wireless lan devices and turn on the wireless extensions.
* and finally a Kconfig option to enable/disable this all.
