[Bug 1640283] [NEW] Unchanged trace is not detected as such, and fails tests

 

Public bug reported:

On the gate, tests that run ovs-appctl ofproto/trace (i.e. simulate a
packet passing through the OVS/OpenFlow pipeline) do not detect that the
packet is unchanged unless the flow states 'unchanged.' This behaviour
does not work in OVS 2.5.0, and was fixed in OVS 2.5.1.

Reproduction: See 'check experiment' tests, fullstack-xenial, test_install_flood_to_tun.
Reproducible on: Ubuntu Xenial, or any installation with OVS 2.5.0.

** Affects: neutron
     Importance: Undecided
     Assignee: Omer Anson (omer-anson)
         Status: In Progress
