afdbc75bf9 Resolve SDV reported "defect" 
NdisMGetDeviceProperty() should always return non-NULL
FunctionalDeviceObject according to _Outptr_opt_. An explicit
FunctionalDeviceObject NULL check has been added to keep the SDV happy
and not calling our driver "defective".

ca120aa1c0 Declare NDIS 6.83 compliant 
After confirming with Microsoft Documentation that Wintun is already
NDIS 6.83 compliant, we declare it so.

In order to build NDIS 6.83 miniport driver, WDK for Windows 10, version
1903 is required: documentation updated.
