>I am wondering if it was put in to the kernel for 5.10 and then left "off by default" until this year.
Any idea how we might check that?

I'm fairly certain we've seen it on `Linux 5.15.0-1017-aws x86_64`.
I could, i guess, try to load an old kernel. i tend to clean out /boot, and if the package manager deletes my kernel source all i have is a .config. I would lean toward .config diffs, but it is possible that my distribution kernel maintainers made specific patches that made this networking stuff "optional" - as is spectre and rowhammer and other speculative execution mitigation "optional". I just know my torment with networking started about 5 months ago at the closest. I didn't upgrade kernels between February and May 31st of 2022, so if it happened in there, i wouldn't be able to track that down without some sort of distro-specific archive of kernel releases.
