1) Regarding rx queues: what does "ls /sys/class/net/eth0/queues" show ?
$ ls /sys/class/net/eth0/queues rx-0 tx-0
2) can you try setting affinity for working only with CPU3 and see what happens after some traffic is sent by cat /proc/interrupts?
# echo 8 > /proc/irq/19/smp_affinity # cat /proc/irq/19/smp_affinity 08 $ cat /proc/interrupts |grep eth0 19: 20635 78 387 1857 IO-APIC-fasteoi eth0 $ cat /proc/interrupts |grep eth0 19: 20635 78 387 3041 IO-APIC-fasteoi eth0 Now only, CPU3 is processing the packets. So, i think, this driver(pcnet32) is not using multiple Rx Queue.
