Hi,
5. Contributing Code to DPDK — Data Plane Development Kit 16.04.0 documentation<https://dpdk.readthedocs.io/en/v16.04/contributing/patches.html#:~:text=The%20mailing%20list%20for%20DPDK%20development%20is%20dev%40dpkg.org.,is%20also%20worth%20registering%20for%20the%20DPDK%20Patchwork>
Please refer to this link. And about the description, I think it would be good to describe that the real issue is missing to set the proper value in the error branch.
