| Doc Text: |
Previously, the first packet of a new connection using an OVN logical router was used to discover the MAC address of the destination. This resulted in the loss of the first packet on the new connection.
This enhancement adds the capability to correctly queue the first packet of a new connection, which prevents the loss of that packet.

As mentioned in the u/s ML discussions, this is a known limitation and it is by design. It has to be fixed in openvswitch. https://mail.openvswitch.org/pipermail/ovs-discuss/2018-March/046409.html Since the fix should to go to openvswitch first, I'm changing the component for this bz. Updating Target Milestone to z3 for all Modified medium bugs fix verified: overcloud) [stack@undercloud-0 ~]$ ssh root.0.222 The authenticity of host '10.0.0.222 (10.0.0.222)' can't be established.
