At the packet level, this is a core problem that SDN has to solve.  When
we're running in an SDN environment, we should just hand off responsibility
for QoS to them.  Otherwise, we should probably steal their algorithms.  ;)
I believe there are some experts elsewhere at Red Hat whose brains we can
and should pick.
