The tcpdump file I used was very simple - the original filter was
tcp port 79

so I am puzzled as to why there may be differences. I will be able to run
more tests tomorrow on various tcpdump capture files. This was just one I
had on the local disk.

I will start building a series of tcpdump data files with various filter
options and see what that does to help debug. I would still prefer to try on
a 'known good' platform first and make comparisons after.
