You can tell which CPU is processing the packets by looking at /proc/interrupts. You can also control the affinity of the interrupts via /proc/irq/$IRQ/smp_affinity. There is a script included with the driver from SF that will map the queues 1:1 to the CPUs and if you have Flow Director enabled it will also receive the packets on the same queue that transmitted them.
