Hello, devs! I hope you all are doing well! I am currently working on a new patch version for "[PATCH v2] lib/net: add MPLS insert and strip functionality". However, I am facing an error when running the devtools/test-meson-build.sh script. The error is related to unused functions in rte_mpls.h that is causing warnings to be treated as errors, leading to the build failure. Following is the error snippet:

As per my understanding, I need to use these new functions in lib/net/rte_net to remove this warning, but I believe that the tests in the app/ directory should be sufficient. Could you please suggest a workaround to remove this warning? I would greatly appreciate any guidance or assistance you can provide.
