[dpdk-dev] ksoftirqd when using KNI

I'm a newbie and testing DPDK KNI with 1G intel NIC.

According to my understanding of DPDK documents,
KNI should not raise interrupts when sending/receiving packets.

But when I transmit bunch of packets to my KNI ports,
'top command' shows ksoftirqd with 50% CPU load.

Would you give me some comments about this situation?
