I can't even remember if it ever got in or not - but sfq hashing got the
same flexibility - from man tc-sfq

...

It is possible to use external classifiers with sfq, for example to hash
traffic based only on source/destination ip addresses:

# tc filter add ... flow hash keys src,dst perturb 30 divisor 1024

        Note that the given divisor should match the one used by sfq. If
you have changed the sfq default of 1024, use the same value for the
flow hash filter, too.
