Code review comment for ~harald-jensas/cloud-init:bug/1847517

thanks for the well done bug report and merge proposal!

Please add a test to the unfortunately long and difficult to follow tests/unittests/test_net.py .

Also, as this is your first submission:

To contribute, you must sign the Canonical Contributor License Agreement
(CLA) [1].

If you have already signed it as an individual, your Launchpad user will
be listed in the contributor-agreement-canonical launchpad group [2].
Unfortunately there is no easy way to check if an organization or company
you are doing work for has signed. If you are unsure or have questions,
email <email address hidden> or ping powersj in #cloud-init channel
via freenode.

For information on how to sign, please see the HACKING document [3].

Thanks again, and please feel free to reach out with any questions.
