[Bug 2067889] Re: DPDK 23.11.1 / OVS 3.3.0 cause test failures

[Christian Ehrhardt ]

The only very unique entry I got here in those logs of the dpdk enabled
openvswitch in the bad case was:

00001|dpdk|ERR|TELEMETRY: Socket write base info to client failed

Not sure where to go with that, is that from the switch or the client even?
I might need to reach out if there are any known issues where, now that I have
some pointers, this rings a bell.

  The logs are messy to read if not used to it, this is a try at debugging what is going wrong.
  So far it seems other people have retried 14 times, and 14714 fail at the same tests - I think there is a real issue.

  As shown below, one can find always these fail:
  4: OVS-DPDK - ping vhost-user ports                FAILED (system-dpdk.at:148)
  5: OVS-DPDK - ping vhost-user-client ports         FAILED (system-dpdk.at:224)
  16: OVS-DPDK - MTU increase vport port              FAILED (system-dpdk.at:609)
  17: OVS-DPDK - MTU decrease vport port              FAILED (system-dpdk.at:651)
  20: OVS-DPDK - MTU upper bound vport port           FAILED (system-dpdk.at:767)
  21: OVS-DPDK - MTU lower bound vport port           FAILED (system-dpdk.at:809)
