I think you are right on this so forget about my thought. Maybe as
an additional input it might be worth mentioning that I have patches
ready to a) make the sfq depth adjustable and b) hash algorithm
selection to a few builtin ones and additional to read theh hash
from tc_classid set by an action. A real world example where this
is useful is for routers primarly doing SNAT without any own local
traffic where hashing algorithm primarly based on the source port
makes a lot more sense.
