Bug Description
Shaker north-south scenario (openstack/
Description of the environment: MOS 9, ISO 415 and ISO 481, Neutron ML2, VxLAN, DVR, 6-nodes cluster. However it was not present on ISO 401 deployed on KVM.
The same can be reproduced manually with iperf3. The throughput between instance with fip and another instance with fip is good.
Steps to reproduce: run Shaker openstack/
Expected results: the throughput should be at least Gb for 1Gb interface
Actual result:
