SRIOV mechanism driver doesn't support flat networks

[Maru Newby]

The SRIOV mechanism driver only supports vlan networking at present. It would be useful to support flat networking as well.

I have a report that omitting the vlan id from the libvirt xml (by commenting out [1]) allows flat networking to work. It's not clear whether neutron providing a vlan id of 0 would have the same effect.
