Should I guess that, from the flood of subsequent emails about patching
netem that it is not currently possible to do netem and hfsc/sfq on
ingress traffic using the currently available tools? 

It's definitely netem on the ingress.  When I run it on egress and
disable it on ingress, I do not have the problem.  But, I see no what of
getting the netem traffic into or out of SFQ.  Thanks - John
