Registering Optional NDIS 6.0 Protocol Driver Entry Points
NDIS calls the ProtocolSetOptions function during a protocol driver call to the NdisRegisterProtocolDriver function. If a driver does not register optional services, set the entry point for ProtocolSetOptions to NULL in the NDIS_PROTOCOL_DRIVER_CHARACTERISTICS structure. To provide additional entry points, the protocol driver calls the NdisSetOptionalHandlers function from ProtocolSetOptions.
