This is okay as long there is no Xenstore interaction required when the
interface has been setup completely (i.e. only defining the needed
offset for XDP is fine, enabling/disabling XDP at runtime should not be
done via Xenstore IMO).

And please, no guest type special casing. Please replace "Linux" by e.g.
"The guest" (with additional tweaking of the following sentence).
