## Contributing
### Issues
* If reporting a bug, please document how to reproduce it.
* Please always test the latest master branch.
* Finding the commit which introduced the problem helps (bisecting).
* Document the kernel and distribution that were used.
* Tests should ideally use network namespaces to not interfere with the rest of the system.

### Pull requests
* If fixing a bug, please document how to reproduce it.
* Finding the commit which introduced the problem helps (bisecting). Add `Fixme:` tag.
* If adding a feature, please describe why it's useful to add it.
* Commits should be signed: `Signed-off-by: Your Name <me@example.org>`, see
https://www.kernel.org/doc/html/latest/process/submitting-patches.html#sign-your-work-the-developer-s-certificate-of-origin.
* Although the coding style for most tools is ancient, new code should follow the Linux kernel coding style.
See https://www.kernel.org/doc/html/latest/process/coding-style.html.
* To update the code in the pull request, use `git push -f`. Do *not* open a new pull request.

### Reviewers
* Reviewers are very welcome. Post your comments or add `Reviewed-by: Your Name <me@example.org>`.
