            What to do when verification of an artifact checksum fails. Valid values are
            {@code ignore},
            {@code fail} (default for Maven 4 and above) or
            {@code warn} (default for Maven 3).

  network plugins which was first widely noticed in 1.16 (though some users saw it
  earlier than that, possibly only with specific network plugins). If you were previously
  using ethtool to disable checksum offload on your primary network interface, you should
  now be able to stop doing that. ([#92035](https://github.com/kubernetes/kubernetes/pull/92035), [@danwinship](https://github.com/danwinship)) [SIG Network and Node]
