Cheers

I am not sure about binding packets to CPUs, but binding by protocol families would be quite nice I think. Starting by binding specific IRQs to certain set of CPUs would be much better way to get there since it would go well with our cpu-locality concept, starting from the interrupt and right all the way up to a process.

ithread_irq11 -> netisr_cpu1 -> tcpthread_cpu1 -> process on cpu1
