    Description

      This is the direct consequence of the new https://jira.fd.io/browse/VPP-2012 (preventing CSIT from setting high enough MTU) triggering the old https://jira.fd.io/browse/VPP-1876 (explaining the decreased performance).

      It is possible that a new CSIT approach to max frame size discussed in https://jira.fd.io/browse/CSIT-1797
      will enable a new workaround, but currently there is no way to address this regression only on CSIT side.
