Title:
  ovs dpdk system tests fail due to early exit of dpdk-testpmd
  application

Status in dpdk package in Ubuntu:
  New
Status in openvswitch package in Ubuntu:
  New

Bug description:
  Since DPDK 22.11.3 the dpdk-testpmd application will exit immediately
  when run in non-interactive mode.  This commit looks suspicious [0].

  While this is an upstream DPDK bug there is patches in-flight [1] in
  OVS to change the way the dpdk-testpmd application is invoked.

  Until that lands we can work around this issue by passing `--stats
  period N` or `--interactive` to dpdk-testpmd.
