I suspect libtopo could be used to provide the needed information, however it's completely undocumented and even the comments seem to assume you already understand how to use the lib, so I can't offer much in the way of implementation details. What'd be nice is to go even further, and not just network devices, but having the information for controllers as well would be good. It might even be nice if enough information existed that people could contribute modules for 3rd party servers as well (obviously might not work in all cases, but for a lot of stuff it might).
