#8 VLANs support inside virtual machines

[Fermín Galán]

A way to configure a VLAN interface in a virtual
machine, so it can has subinterfaces like eth1.10,
eth0.13, etc.

To do so, vconfig should be added to the root_fs
package (if not present yet) and a modification to the
DTD should incluye a way to define VLANs for the
virtual machines (for example a attribute to <if>).
