l2switch/arphandler/core/PacketDispatcher.java line 102: Wrong in_port in PacketOut message

As per OpenFlow Spec 1.3 section A.3.7 Packet-Out Message:

uint32_t in_port; /* Packet's input port or OFPP_CONTROLLER. */

But floodPacket function at l2switch/arphandler/core/PacketDispatcher.java line 102 sets in_port as controllerNodeConnector which in turns sets OFPP_LOCAL instead of input port or OFPP_CONTROLLER.

Solution:
change sendPacketOut(payload, controllerNodeConnector, ncRef);

to

sendPacketOut(payload, origIngress, ncRef);

which will set input port.
