Junos docs say, "The hash-computation for the forward and reverse flow must be identical." They go on to detail how to configure a link index to each physical port and that Trio chipsets require symmetrical load-balancing. 

That sounds a bit weird... why should the device care how the other
end balances its packets?  Never heard anyone state this, and I can't
come up with a reason why.
