Hi Ben, My intention is just if any different version is coming on switch then it should have handle capability (as per openflow spec 1.0 also) . I think the version in switch's "error" packet should be the one which switch is using so that other (controller) would come to know the right version. It was working before in OVS 1.2.2 Just need to know is there any specific reason to change this design?
