Hi, I am exploring traffic captures from tests with Mininet/Openvswitch 2.5 and OpenDaylight controller, and try to understand why the transaction ID (xid) field in PACKET_IN messages is always zero, while for the rest message types (either switch- or controller-initiated) it is correctly set to some unique value, which is reused in the reply as it should. Am I missing something basic here specified in the OF protocol, or is it and implementation decision of OVS?
Thanks in advance, Nikos
