NDIS Filter Drivers

Filter drivers are supported in NDIS 6.0 and later versions. You should use filter drivers instead of filter intermediate drivers. For more information about intermediate drivers, see NDIS 6.0 Intermediate Drivers.

The following sections introduce filter drivers and describe how to write and install filter drivers:

Roadmap for Developing NDIS Filter Drivers

NDIS Filter Driver Installation

This quote can be found in the index of the WDK documentation under "NDIS Filter Drivers". And here is the link to MSDN. Although the WDK docs you install locally and this link are not identical. All you need to know is on these pages - except that you should have preliminary knowledge of drivers and kernel mode development for Windows.
