I.e., you have an external tool that's providing link-layer frames, and 
you want Wireshark or WinDump to analyze them?

If the external tool writes the frames to its standard output, and can 
be run from the command line, then you should be able to have WinDump 
analyze them:

	{external-tool} | windump -r -

For Wireshark, it's a bit more complicated; on UN*X, you can do it with 
a named pipe file, but I'm not sure whether you could send the standard 
output of a program to a named pipe on Windows.
