Please make sure you run make htmldocs when changing docs,
this will warn.

Physical port has VFs? My knee jerk reaction is that allocating
resources via devlink is fine but this seems to lean a bit into
forwarding. How do other vendors do it? What's the mapping of VFs
to ports?
What do you suggest should happen when user enables switchdev mode?
