[lvs-users] the problem of SMP IRQ Affinity

[cing]

the next is my config of cpu irq affinity, the model of director is DR

no rx vectors found on eth0
no tx vectors found on eth0
eth0 mask=1 for /proc/irq/102/smp_affinity

problem:
this my load of cpu interrupt, why it  concentrates in front of 16 cpus ?
