I won't defend other vendors' implementation. Even if LRO was
not turned off for bridge/forwarding, we still wouldn't accumulate
those remote flows because the dest IP address is not configured in
firmware in our case. This is the reason why we have a inet
notification listener (to tell firmware about local addresses).
