I also see references to 4.9.17 in Documentation/concepts/overview.rst, though maybe that document should just point over to here for the kernel requirements now instead of having its own version content / text?
While you're at it, you may consider adding RancherOS per #9825 as well.
Couple of minor fixup requests below.

When available we also use LRU (Least Recently Used) hash maps with BPF, which appeared in kernel 4.10. But as far as I know we don't have any specific documentation on the topic (not sure it makes a difference to the user, other than for performance), so not sure if worth adding in this table.

I think for current usage (existing maps) we work around the lack of LRU by just creating a hashmap and spinning up a garbage collection controller in the cilium-agent.
