I'm trying to work in the open, and go upstream early (or at least I think that understand what these things mean.)  If the community doesn't want functions that have no callers (and I understand that, too) then how should I provide them to the NIC vendors?

You add the functions in a patch series along with the NIC driver that
uses it.  We don't add functions with no callers, sorry.

hope this helps,
