LGTM, but feels to risky to merge during the merge window.
Since we're changing semantics we should let this sit in linux-next
for at least a week. Please repost in Sept.

BTW please carefully review clashiko feedback:
https://netdev-ai.bots.linux.dev/sashiko/#/patchset/20260814-netcons_ipv6-v3-7-bc0915e8c75f@gmail.com
It marked as preexisting the problem of IP versions diverging but 
I think it's relevant (patch 2)?
