tcpstat -- tcpstat reports certain network interface statistics<hr>
<a href="http://www.frenchfries.net/paul/tcpstat/">http://www.frenchfries.net/paul/tcpstat/</a><hr>
tcpstat reports certain network interface statistics much like vmstat
does for system statistics.

tcpstat gets its information by either monitoring a specific interface,
or by reading previously saved tcpdump data from a file.
