2. download the tar file and uncompress to any directory. This tar file is from kernel. It is in samples/pktgen/ 3. cd pktgen 4. pktgen_sample02_multiqueue.sh -i ethx -s size -t cpu_number If size is set to a big number, the similar defect will occur. Adjust this size to a appropriate number, my defect will not occur. In the test, I found some types igb nic, such as i210, will work well no matter the size is a big number. some nic, such as 82580, it will not work well if the size is too big. As such, I think my problem results from the hardware and the big size triggers this problem. I hope this can help us all.
