Hello Zhoumin, It looks like Loongarch CI failed to apply this patch, but it worked at the other labs and locally for Serhii when they were checked out to next-net.
Maybe your CI did not choose next-net, the right branch? I remember you saying your CI is based on a fork of the dpdk-ci repo. Perhaps the pw_maintainers_cli.py script for choosing the right branch to apply on, is outdated in your fork. https://git.dpdk.org/tools/dpdk-ci/tree/tools/pw_maintainers_cli.py Can you take a look? Thanks.
