✅ Formalities

• I have reviewed the CONTRIBUTING.md file for detailed contributing guidelines.

If your PR contains a patch:

• It can be applied using git am
• It has been refreshed to avoid offsets, fuzzes, etc., using

  make package/<your-package>/refresh V=s

• It is structured in a way that it is potentially upstreamable
  _{(e.g., subject line, commit description, etc.)
  We must try to upstream patches to reduce maintenance burden.}

You are not following the contribution guidelines again, wrt commit message, cherry-picking to stable, and package release bumping.

This goes for LuCI PRs as well.

I've told you in the LuCI PR (which you have not tested against the OpenWrt packages) that it's a NACK from me, yet you still proceeded to open PRs here. It's still a NACK.
