That's nothing to be worried about. Tcpdump only snaps a certain
amount of each packet (68 bytes per default, I believe). This is
enough to get information concerning IP, ICMP, TCP and UDP, but may
not be enough for other protocols. Use tcpdump with a greater
snaplength, e.g. "tcpdump -s 200" instead of simply "tcpdump".
See the man page for tcpdump(1) for more information.
