Are you sure ethtool is the right interface for this?
Yes.
Me thinks the kernel should just do the right thing automatically for this, by distributing the flows over CPUs.
How the work, and what kind of work, should be distributed across the machine is the user's business. Or maybe we should just get rid of all of those NUMA knobs we have too? We've discussed this before and Jeff Garzik and I already told everyone that we want to make this configurable and ethtool is the way to do it no matter how adhoc and device specific the interfaces might end up being. Please don't send submitters mixed messages like this after we've told them to do things this way, it only leads to discouragement for new contributors.
