[Cake] flow_hash vs host_hash

[David Lang]

only if the bottleneck router that needs to do the queuing is directly adjacent 
to the endpoints.

Yes, home routers commonly fit this definition, but since the usual case is a 
router/modem from the ISP with a wifi router plugged into it and the endpoints 
attached to the wifi router (wired or wireless), the ISP router/modem which has 
the actual bottleneck and should be doing the queuing isn't going to actually 
see the endpoint mac addresses.
