Yup, replaced this function with 'return 0' and my problems are gone.
(Well okay, this problem is gone, and you're probably not interested
in my personal problems. :))

Obviously just completely disabling QoS multiple queues is not the
right long term fix, but as Dave pointed out, it wasn't clear the code
there was exactly what we want anyway, so I won't feel too guilty
about it.  Meanwhile, hopefully someone with deeper knowledge than me
can figure out what's with the IVs.
