tun flow entry 'updated' fields are written when receive every packet. Thus if a flow is receiving packets from a particular flow entry, it'll cause false-sharing with all the other who has looked it up, so move it in its own cache line and update 'queue_index' and 'update' field only when they are changed to reduce the cache false-sharing.
