    <para>
      <application>NetworkManager</application> is a set of co-operative
      tools that make networking simple and straightforward. Whether you use WiFi,
      wired, 3G, or Bluetooth, NetworkManager allows you to quickly move from
      one network to another: Once a network has been configured and joined
      once, it can be detected and re-joined automatically the next time it's
      available.

      If you wish to run the tests, check that at least the following options
      are enabled in the kernel configuration. Those options have been
      determined to be necessary, but may not be sufficient. Recompile the
      kernel if necessary:
    </para>

    <!-- Ethernet Teaming support is potentially optional, but I didn't
         run the tests again to test that. It was needed to convince one of
         the Linux Platform tests to move farther along because otherwise
         RTNETLINK would respond with an Error 95 - unknown device type.
         This would cause the test to fail early on in the process.

         [pierre, Nov 2022]: I cannot tell whether these options are
         the only ones that are needed. They are the options I had to add
         in order to have some tests pass. But I already had some other
         options set for packet filtering (iptables), that may not be
         available by default and may be necessary. Even with the options
         below still one test (test-route) fails.-->
