But since my friend is an experienced engineer, I feel like it may be better (for the community) to ask this in the list. We are using dpdk-stable-18.11.6 and igb_uio. What are we doing wrong? If it is not a FAQ, I can test it again with more recent stable, and will report the details. Thanks. Best, Yasu
