Hey Sachin do you know why this STP module would not work with zaku? I'm asking because I have actually used it (not too thoroughly to be honest) and didn't immediately see any issues. Is it the fact that routing does not use OFP_FLOOD, so it wouldn't work with routing, or is it an issue with the STP module itself?
