share/man/man4/ip6.4
507	I'm not sure if we should include the OS version here, since we don't want to MFC this revision to older versions.
517	IMHO, there is no need to mention OpenJDK here and state that it is widely adopted.

This revision is now accepted and ready to land.Feb 19 2026, 8:49 PM

There seems to be significant demand from the user base for this "feature", probably because the OpenJDK is the main consumer of it, and it is doing something in-kernel that the OpenJDK socket shims handled themselves historically anyway.

I added some suggestion, but they are IMHOs. I'd suggest to wait for approval from a doc committer. @ziaee maybe you?

share/man/man4/ip6.4
199–224	IMHO, the content suggested for addition actually belongs to this part of the manual page.
507	Agreed. AFAIK, a content chapter of a manual page shall not talk about FreeBSD versions. It should just list factual information that matches the branch. The information about which version introduced what can be optionally added to the `HISTORY` chapter at the end of the manual page.
517	Yep, mentioning a particular out of the project program is not desired. Also I'd suggest to remove work "undocumented", cause now it is documented.

Address all review comments, caveat the addition in the HISTORY section.
