//
// flodo.c: simple network flow sampling tool
//
// i frequently want to know what the top few network flows are... and yet
// there didn't seem to be any tool which was as simple to use as "vmstat"
// or "iostat".  this tool fills that void for me.
//
// with the default options flodo will dump the top 20 flows every 5 seconds.
//
// flodo is quite basic at this point, understanding only ethernet frames,
// ipv4, tcp, and udp.
//
// flodo can't even do reverse DNS and doesn't bother mapping port numbers
// to services or display icmp or ethernet protocol names.
