Hi, the next error came out this time on your new patch
in my local environment, when switch is connected.
Error in the datapath None from ('127.0.0.1', 54964)
hub: uncaught exception: Traceback (most recent call last):

Is this right?
@@ -50,6 +51,7 @@ class ProtocolDesc(object):
if version is None:
version = max(_supported_versions)
self.set_version(version)
+ self.supported_ofp_version = _supported_versions
thanks.
