[libvirt] [libvirt PATCHv3 10/10] support multiple static IP addresses

[David L Stevens]

	This patch adds support for multiple static IP addresses in a
comma-separated list. For example:

    <interface type='network'>
      <filterref filter='clean-traffic'>
        <parameter name='ip_learning' value='none'/>
        <parameter name='IP' value='10.0.0.1,10.1.0.7,10.0.3.8,10.0.9.244'/>
      </filterref>
    ...
