A typical XML representation of the virNWFilterBindingDefPtr struct
looks like this:
<filterbinding>
<owner>
<name>f25arm7</name>
<uuid>12ac8b8c-4f23-4248-ae42-fdcd50c400fd</uuid>
</owner>
<portdev name='vnet1'/>
<mac address='52:54:00:9d:81:b1'/>
<filterref filter='clean-traffic'>
<parameter name='MAC' value='52:54:00:9d:81:b1'/>
</filterref>
</filterbinding>
