    M tests/ofproto-dpif.at

  Log Message:
  ofproto-dpif-xlate: Fix recirculation when in_port is OFPP_CONTROLLER.

Recirculation usually requires finding the pre-recirculation input port.
Packets sent by the controller, with in_port of OFPP_CONTROLLER or
OFPP_NONE, do not have a real input port data structure, only a port
number.  The code in xlate_lookup_ofproto_() mishandled this case,
failing to return the ofproto data structure.  This commit fixes the
problem and adds a test to guard against regression.
