[ubuntu] Can't change ethernet card smp_affinity when using bonding driver

view story

http://ubuntuforums.org – I'v got a server with 2x1Gb nics, 8 cores CPU. The nics are bonded using bonding driver with mode 803.2ad. I faced the problem with changing network cards' affinity . The irq interrupts coming from nic cards are spread to 8 cores. I tried to limit the number of irq request against 2 cores of the CPU by editing /proc/irq/devicIRQXX/smp_affinity, but it did not work for me. Could you please help me to limit the irq request to the 2 cores. (every nic card to 1 core) here is the output of the file /proc/interrupts Quote: CPU0 CPU1 CPU2 CPU3 (Hardware)
