I appreciate that network tuning is hard, most people get it wrong, and nobody agrees on the right answer. So rather than fixing existing tools or writing new userspace tools to do network tuning, you want to hard code one policy manager in kernel with a /proc interface. Why not make a good userspace tool (like powertop). There are also several IRQ balancing programs, but since irqbalance was championed by one vendor others seem to follow like sheep. I agree that this a real concern but the implementation of this leaves much to be desired and discussed. Why can't this be done outside of the kernel.
