Alex and I had a quick chat about this, I think we can work around
the difficulties with duplicating the behavior in SW by enforcing
that the action can only be used with skip_sw. Either skbedit or
Alex's suggested approach with act_mirred. Or new hw-only action.
Alex pointed out that it'd be worth documenting the priorities of
aRFS vs this thing, which one will be used if HW matches both.
