I'm not sure this belongs in this particular thread but I was interested in how you're planning on doing this? Is there going to be a way for userspace to specify which traffic flows they'd like to direct to particular cpus, or will the kernel try to figure it out on the fly?
We have application guys that would like very much to be able to nail specific apps to specific cores and have the kernel send all their packets to those cores for processing.
