27 /* This module provides statistics about two merged capture files, to find packet loss,
28 * time delay, ip header checksum errors and order check.
29 * It's also detecting the matching regions of the different files.
30 * After the coloring is set Info column can be sorted to create zebra effect.
32 * The packets are compared by the ip id. MAC or TTL is used to distinct the different files.
