The Modular L2 Plugin uses drivers to support separately extensible
sets of network types and of mechanisms for accessing networks of
those types. This is an initial implementation that has been tested
with the openvswitch and linuxbridge agents, and should also work with
the hyperv agent. See quantum/plugins/ml2/README for details.
