how well does it work with Linux? Sounds like all i need to do is turn
on some BIOS feature. 
One of the negatives with multiqueue nics is because the core selection
is static, you could end up overloading one core while others stay idle.
This seems to steal cycle capacity from the idle cores and gives it to
the busy cpus. nice. So i see it as a boost to multiqueue.
