        !            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>
