Registering Optional NDIS 6.0 Entry Points for Miniport Drivers
NDIS calls the MiniportSetOptions function during a miniport driver call to the NdisMRegisterMiniportDriver function. If a driver does not register optional services, set the entry point for MiniportSetOptions to NULL in the NDIS_MINIPORT_DRIVER_CHARACTERISTICS structure. To overwrite the default entry points, the miniport driver calls the NdisSetOptionalHandlers function from MiniportSetOptions.
