                     19: <p>NetFlow is a protocol for exporting aggregated traffic information
                     20: with UDP packets flow. NetFlow is generated by <code>ng_netflow(4)</code> node.
                     21: To enable NetFlow on a particular interface <code>netflow-in</code> or
                     22: <code>netflow-out</code> options should be used. Best practice is to enable
                     23: netflow on every interface in system in only one direction:
                     24: incoming for "ingress" flow or outgoing for "egress" flow.</p>
                     25: <p><b>Note:</b> Netflow configuration is global for the daemon, 
                     26: so it must be done before first bundle get connected.</p>
                     27: <p><b>Note:</b> This feature is available only on FreeBSD 6.0-RELEASE
                     28: and newer. NetFlow v9 supprted only on FreeBSD 9.0-RELEASE and newer.</p>
