Porting Miniport Driver Unload Operations to NDIS 6.0
For NDIS 6.0, miniport drivers must specify a MiniportDriverUnload function entry point in the NDIS_MINIPORT_DRIVER_CHARACTERISTICS structure. NDIS 6.0 drivers do not call the NdisMRegisterUnloadHandler function.
In MiniportDriverUnload, a miniport driver must call the NdisMDeregisterMiniportDriver function to deregister the miniport driver. The driver passes NdisMDeregisterMiniportDriver the handle that it obtained at NdisMiniportDriverHandle when it called the NdisMRegisterMiniportDriver function.
