[Fermín Galán]

Extend <net> in order to allow PPP and QoS switch,
something like:

<net type="ppp">
<tc>
<delay order="yes">
<normal average="200" deviation="20"/>
</delay>
<drop>
<constant value="0.003"/>
</drop>
<duplication>
<constant value="0.0002"/>
</duplication>
</tc>
</net>

<net type="switch">
<tc>
<source>
<ipv4>192.167.77.7</ipv4>
</source>
<delay order="yes">
<normal average="200" deviation="20"/>
</delay>
<drop>
<constant value="0.003"/>
</drop>
<duplication>
<normal average="0.0002" deviation="0.0002"/>
</duplication>
</tc>
<tc>
<source>
<ipv6>11:11:11:11:11:11:11:11:11:11</ipv6>
</source>
<destination>
<mac>22:11:11:11:11:11</mac>
</destination>
<delay order="yes">

</delay>
<drop>
<constant value="0.003"/>
