That's true. Still, couldn't we find a better solution?

I know that netlink isn't designed for this kind of things. But if we
don't have any other idea, I'd still prefer that over a dedicated
network interface.

If some program needs to get frames it injected back with a status,
there should exist an easy way to determine which status corresponds
with which frame. If there is no need to determine this, what is the
reason for returning back injected frames in the first place?
