No, but I can suggest that, of the source files in the packetNtx/driver directory of the WinPcap source, Openclos.c, Packet.c, Read.c, and Write.c may have to be modified, and some others might have to be modified as well.  You might have to change some of the user-mode library code in packetNtx/Dll, and maybe even the packet-win32.c code in wpcap/libpcap.

Convert the code from a transport driver:

to a lightweight filter driver:

You will first have to learn about NDIS and writing kernel-mode code for Windows if you want to do this.  (No, I can't teach you how to do that.)
