Quantum L2 Linux Bridge Plugin

The proposal is to implement a Quantum L2 plugin that configures a Linux Bridge to realize Quantum's Network, Port, and Attachment abstractions. Each Quantum network would map to an independent VLAN managed by the plugin. Sub-interfaces corresponding to a VLAN would be created on each host, and a Linux Bridge would be created enslaving that sub-interface. One or more VIFs (VM Interfaces) in that network on that host would then plug into that Bridge. To a certain extent this effort will achieve the goal of creating a Basic VLAN Plugin (as discussed in the Essex Summit) for systems which support a Linux Bridge.
