Sometimes you have a capture file that has many duplicate frames because of how the capture was made, and its convenient to ignore the duplicates so you can concentrate on the data and not all the TCP warnings. This adds a preference in the "Protocols" section to ignore duplicates. This currently only works while reading a capture file *not* during a live capture.
