VOID NdisRawReadPortUlong( IN ULONG Port, OUT PULONG Data );
This function runs faster than the NdisImmediateReadPortUlong function because it need not map a bus-relative I/O port address onto a host-dependent logical port address at every call.
A driver that calls this function can run at any IRQL.
