This is a newer version of the series started by Geliang, now making
them more uniform on how the NL errors are set, and giving more hints to
the userspace about what's wrong.

Hi Matthieu,

Thank you for your modifications, that's great!

Our CI did some validations and here is its report:

- KVM Validation: normal: Success! ✅
- KVM Validation: debug: Success! ✅
- KVM Validation: btf-normal (only bpftest_all): Success! ✅
- KVM Validation: btf-debug (only bpftest_all): Unstable: 1 failed test(s): bpftest_test_progs-no_alu32_mptcp 🔴
- Task: https://github.com/multipath-tcp/mptcp_net-next/actions/runs/12547335119

Initiator: Patchew Applier
Commits: https://github.com/multipath-tcp/mptcp_net-next/commits/70fec43cc6e0
Patchwork: https://patchwork.kernel.org/project/mptcp/list/?series=921412


If there are some issues, you can reproduce them using the same environment as
the one used by the CI thanks to a docker image, e.g.:

    $ cd [kernel source code]
    $ docker run -v "${PWD}:${PWD}:rw" -w "${PWD}" --privileged --rm -it \
        --pull always mptcp/mptcp-upstream-virtme-docker:latest \
        auto-normal

Please note that despite all the efforts that have been already done to have a
stable tests suite when executed on a public CI like here, it is possible some
reported issues are not due to your modifications. Still, do not hesitate to
help us improve that ;-)
