driver_ndis: Detect Native 802.11 drivers (NDIS 6, Vista)

Browse source 
This is just there very first step on being able to do something with
wireless LAN on Vista. There is some example code for requesting a scan,
but it does not work in its current form. Anyway, this adds a wpa_printf
noting that Native 802.11 drivers are not yet supported.
