You will need to figure how EXT-427 and NXT_RESUME will play
together, as both may be used to set metadata.
With EXT-427, it's possible to dela with metadata continuation
entirely from the OXM part of packet-in and packet-out. And because
OXM is extensible, there is further tricks you can play there.
