v4:
 - squash patch 1/5 and 3/5 in v3 together as Matt suggested.
 - a new squash-to patch to drop mptcp_subflow_active declaration in
   bpf_burst.

v3:
 - drop bpf_iter__mptcp_subflow, __diag_push, __diag_pop and
 __diag_ignore_all
 - drop declarations for bpf kfuncs

v2:
 - update patch 1 as Martin and Andrii suggested.
 - fix warnings and errors reported by MPTCP CI.

This patch set adds a mptcp_subflow type bpf_iter, and self tests.

  bpf: Add mptcp_subflow bpf_iter
  selftests/bpf: Add mptcp_subflow bpf_iter test prog
  selftests/bpf: Add mptcp_subflow bpf_iter subtest
  Squash to "mptcp: add sched_data helpers"
  Squash to "selftests/bpf: Add bpf_burst scheduler & test"

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 (only bpftest_all): Success! ✅
- Task: https://github.com/multipath-tcp/mptcp_net-next/actions/runs/10804410958

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:

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 ;-)
