[PATCH mptcp-next] selftests/bpf: Drop cgroup_fd of run_mptcpify

[Geliang Tang]

From: Geliang Tang <tanggeliang@kylinos.cn>

The parameter 'cgroup_fd' of run_mptcpify() is useless, drop it.

[MPTCP CI]

Hi Geliang,

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): Success! ✅
- Task: https://github.com/multipath-tcp/mptcp_net-next/actions/runs/12783748540

Initiator: Patchew Applier
Commits: https://github.com/multipath-tcp/mptcp_net-next/commits/c6705ddd1ca5
Patchwork: https://patchwork.kernel.org/project/mptcp/list/?series=925578


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

For more details:

    https://github.com/multipath-tcp/mptcp-upstream-virtme-docker


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 ;-)

(detail: s/useless/unused/)

The modification looks good to me, thank you!

Reviewed-by: Matthieu Baerts (NGI0) <matttbe@kernel.org>

Do you want to send it directly to the BPF maintainers, for the
bpf-next/net tree? We don't have other changes that are ready to send.

Or I park it in our tree, and we send it later (no urgency I guess)?

Cheers,
Matt

Please merge it in our tree and send it later together with other bpf
patches.
