Test "TestPacketIn_PacketOut" failed when supposing to match TCP dst Port by flows

[wenyingd]

After switching to OpenFlow1.5, test case "TestPacketIn_PacketOut" is always failed. The observation is the packet can not be packet_in to ofctrl from OVS. Trying to have some investigation, and get these information:

1. The packet generated by ofnet is successfully sent to OVS via packet_out mechnism,
2. The flow installed on OVS does not match TCP dst port on the packet. But If the tp_dst match condition is removed, OVS flow can match the packet with conditions: ip_src+ip_dst+tcp. It seems OVS flow matchers does not work with L4 header on the packet sent from ofnet
3. Tried to calculate TCP checksum and add it in the packet, it does not work either.
