As a side note, note that stateless forwarding like BSD patricie tries
is no longer sufficient. Its no longer just looking up a nexthop, dec ttl,
recompute csum that we are optimizing for.
The dst cache/flowi is the way to go, so theres no going back;-> - we just
gotta make what we have work better.
