Well the value is load balancing of incoming traffic.  Convincing the
remote switch to send traffic on the same link as is used for outgoing
packets is the only way that we have to do load balancing for SLB.

This is really only beneficial for largely unidirectional streams
where we're not outputting traffic that would cause the remote switch
to figure out the correct link by itself.
