You create a new file for it? We already have a doc file here, doc/guides/nics/i40e.rst.

That's good. Someone should probably check if there are other cases like this
in the last 3-4 releases and move them as well.

Sorry. I missed the fact that this was going to a new, i40e, specific file.
I don't think that is a good idea. Maybe there could be a new i40e section
in the known issues doc but I don't think that we should introduce a new
file.

You are right, it's no need to introduce a new file, but Wenzhuo told me an exist doc doc/guides/nics/i40e.rst. What do you think to move the i40e relate known issues to this doc?

Yes. There is an existing "Limitations or Known Issues" section that you
could use:
