Hello,
Thanks for your quick response. The following contains 4 scenarios (0 ~ 3):
scenario 0: packet-out to "select" group and set in_port=CONTROLLER
scenario 1: packet-out to "fast-failover" group and set in_port=CONTROLLER
scenario 2: packet-out to "SELECT" group and set in_port=LOCAL
scenario 3: packet-out to "TABLE" port and set in_port=CONTROLLER
In scenario 1 and 2, my composed packets are sent, but they cannot be sent
in scenario 0 and 3.
