Using tc for true shaping is slightly non-trivial as it shapes only on
egress (which confusingly is towards the VM), and will only police on
ingress. Using ifb is a way around this.
If tc alone won't do the job, I would have thought that rather than
reinvent the wheel and implement rate shaping in netback, it would be
better to hook into the kernel's existing qdisc infrastructure so tc like
tools can be used. This would give much more functionality than a simple
rate.
