I think any stateless/simple thing will do (something along the lines
what 802.1ad does for trunk, a 5 classical five tuple etc).
Having solved the reordering problem in such a stateless way introduces
a loadbalancing setback; you may end sending all your packets to one cpu
(a problem Mr Ye didnt have when he was re-orderding ;->).
cheers,
