NDIS Filter Intermediate Drivers
Note Filter intermediate drivers are not supported in NDIS 6.0 and later. You should use the NDIS filter driver interface instead. For more information about NDIS filter drivers, see NDIS Filter Drivers.
In NDIS 5.x, an NDIS filter intermediate driver exposes one virtual miniport for each underlying miniport driver that is bound to the intermediate driver's lower (protocol) edge.
