Hey Tal, The easiest way to see all the packets per CPU would be to bind the queues to a given CPU they the queue counters would contain the information you're looking for. You could do this with the set_irq_affinity script we provide. Currently the driver doesn't have any structure that is by CPU which would make doing this any other way problematic.
Also the stats aren't incremented in the ixgbe_xmit_frame (hot path) but rather in our service function.
