This is a networking-related patch, so it really needs to go to the

Please word-wrap your changelog text.

This isn't a recognized tag, so shouldn't be expressed this way. If you
want, you can describe your testing setup after the "---" line.

The actual changes are best reviewed by the networking developers.
