The ng_netflow node implements Cisco's Netflow (c) version 5
protocol on router running FreeBSD. ng_netflow listens for
incoming traffic and identifies unique flows in it. Flows are
distinguished by endpoint IP addresses, TCP/UDP port numbers
and ToS. Expired flows are exported out of the node.
All operation is done in kernel: both traffic capturing and
export datagram generation. Exported data contaion almost all
Netflow version 5 fields, except of AS numbers.
