Hello All,

I am a newbie in openvswitch. I captured the packets at the both the
interfaces eth2 and veth1 and observed that packet order is not same. For
example let's consider the tcp packets (SYN, SYN_ACK, ACK). At the eth2
interface the packet are correct but at the veth1 interface the packet
order is changed to SYN, ACK and SYN_ACK.

ovs-ofctl dump-ports-desc br0

 1(eth2): addr
     config:     0
     state:      0
     current:    1GB-FD COPPER AUTO_NEG
     advertised: 10MB-HD 10MB-FD 100MB-HD 100MB-FD 1GB-FD COPPER AUTO_NEG
     supported:  10MB-HD 10MB-FD 100MB-HD 100MB-FD 1GB-FD COPPER AUTO_NEG
     speed: 1000 Mbps now, 1000 Mbps max
 2(veth0): addr:
     config:     0
     state:      0
     current:    10GB-FD COPPER
     speed: 10000 Mbps now, 0 Mbps max
 LOCAL(br0): addr:
     config:     PORT_DOWN
     state:      LINK_DOWN
     speed: 0 Mbps now, 0 Mbps max

cookie=0x0, duration=25551.309s, table=0, n_packets=25485, n_bytes=5694083,
idle_age=319, priority=10,in_port=1 actions=FLOOD

Please let me know what is the issue.

Thanks
