Nox version is 5.0. It works for the version of OpenFlow on the switch (0.8.9).
I used the same function to print ofp_match field and compare the ofp_match value in the flow statistics request and flow statistics reply. They are exactly the same for the 10 fields (wildcards=0). But the returned value is still always 0. If I use wildcards=0xffffffff, then two flows returns (one is for ICMP reply), still with byte_no 0.
