1. modprobe NET_PKTGEN
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.
