Okay, I have attempted to backport this patch to Jammy today. However, the upstream commit mentioned depends on another commit[1]. Unfortunately, I previously looked into backporting that commit in bug 2003250, but as I describe in the bug, it does not behave correctly when backported to Jammy. The same issue came up today when I tested all of these patches together. In particular, the bond is never fully configured on boot, and the subordinate device is never fully re- configured after `networkctl reconfigure`.
I do not have the time to investigate the root cause and write a proper backport for these patches, so this will not be prioritized for 22.04.
