We asked to target these patches at net-next because they don't fix a regression (the encoding never worked correctly), so they are not relevant for stable. Users that require this functionality should upgrade to a new kernel that contains the patches. Regarding the stable-specific patch, in my experience, stable maintainers don't accept such patches and prefer to backport patches from upstream, even if it results in more changes.
