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? -- Moon-Sang Lee, SW Engineer Email: sang0627@gmail.com Wisdom begins in wonder. *Socrates*
