Yeah, I know. It took Debian and Ubuntu a while to fix the packaging. Part  
of the problem was, neutron shipped openvswitch_plugin.ini file instead of  
openvswitch_agent.ini to be loaded by the agent, so deb folks were misled  
by the naming, because plugins are neutron-server things, not agent things.  
This was fixed only recently in neutron, so now that new naming is  
self-explanatory, distributions adopted the correct approach.
