Ok. That seems very reasonable.
So the behavior I am seeing is that I have 4 NICs, but all of the
traffic is being funneled to 1-2 softirq handlers, despite the fact
that the hardware interrupts are being delivered to 4 different CPUs.
Any tips on how to debug this? Or perhaps there is some configuration
step I am missing?
Thanks,
Don

Would you mind giving me a bit of intuition why I can't have a 1:1
mapping of CPUs to NICs?
I didn't say that.
I said that without HW flow seperation support, you can only
expect N cpus to be busy where N is the number of NICs you
have.
