Not sure if that is the correct offending commit, or just the commit that
exposes the already-present issue. I'd add the following also to the commit
log:

Fixes: e024c7e838fc ("net/af_xdp: avoid version-based check for shared UMEM")

That fixline would imply a possible backport though, but no issue has been
seen on versions of DPDK not using C11, so I think we skip backporting this
for now. Putting stable@dpdk.org on CC in case the LTS maintainers have
additional input.

For the code fix itself:
