Comment 3 for bug 1675187

This looks specific to DVR since the legacy code is the only place where we'd actually add the IP to a device, DVR just adds rules and routes now.

I'll have to trace the code, since on the restart of the l3-agent we should be going through code like add_floating_ip() where it could make sure to remove any remnants, or there might be a better place somewhere called only once at startup. Xagent - I remember on IRC you saying you were playing with some patches, feel free to share them if you found something that works.
