Add support for QingHeng CH9200 USB ethernet adapters

[jmarshallnz]

QingHeng CH9200 USB ethernet connectors are relatively common, and support for them have been in the kernel for a long time.

This trivial patch enables the ch9200 module thus allowing users with such ethernet adapters to get a wired network.

Confirmed working with current dev branch as well as backported to 16.3.

Initial discussion for closure here: https://github.com/orgs/home-assistant/discussions/1679

Summary by CodeRabbit

• Chores
  • Enabled CH9200 USB network driver module support in kernel configuration, enhancing hardware compatibility for additional USB-to-Ethernet adapters during the build process.

Hello @jmarshallnz,

When attempting to inspect the commits of your pull request for CLA signature status among all authors we encountered commit(s) which were not linked to a GitHub account, thus not allowing us to determine their status(es).

The commits that are missing a linked GitHub account are the following:

• a1eb81b1b52aab8866422327ef8fba3a18ccad77 - This commit has something that looks like an email address ([email protected]). Maybe try linking that to GitHub?.

Unfortunately, we are unable to accept this pull request until this situation is corrected.

Here are your options:

1. If you had an email address set for the commit that simply wasn't linked to your GitHub account you can link that email now and it will retroactively apply to your commits. The simplest way to do this is to click the link to one of the above commits and look for a blue question mark in a blue circle in the top left. Hovering over that bubble will show you what email address you used. Clicking on that button will take you to your email address settings on GitHub. Just add the email address on that page and you're all set. GitHub has more information about this option in their help center.

2. If you didn't use an email address at all, it was an invalid email, or it's one you can't link to your GitHub, you will need to change the authorship information of the commit and your global Git settings so this doesn't happen again going forward. GitHub provides some great instructions on how to change your authorship information in their help center.

   • If you only made a single commit you should be able to run

     git commit --amend --author="Author Name <[email protected]>"
     

     (substituting "Author Name" and "[email protected]" for your actual information) to set the authorship information.
   • If you made more than one commit and the commit with the missing authorship information is not the most recent one you have two options:
     1. You can re-create all commits missing authorship information. This is going to be the easiest solution for developers that aren't extremely confident in their Git and command line skills.
     2. You can use this script that GitHub provides to rewrite history. Please note: this should be used only if you are very confident in your abilities and understand its impacts.
   • Whichever method you choose, I will come by to re-check the pull request once you push the fixes to this branch.

We apologize for this inconvenience, especially since it usually bites new contributors to Home Assistant. We hope you understand the need for us to protect ourselves and the great community we all have built legally. The best thing to come out of this is that you only need to fix this once and it benefits the entire Home Assistant and GitHub community.

Thanks, I look forward to checking this PR again soon! ❤️

Tip

📝 Customizable high-level summaries are now available in beta!

You can now customize how CodeRabbit generates the high-level summary in your pull requests — including its content, structure, tone, and formatting.

• Provide your own instructions using the high_level_summary_instructions setting.
• Format the summary however you like (bullet lists, tables, multi-section layouts, contributor stats, etc.).
• Use high_level_summary_in_walkthrough to move the summary from the description to the walkthrough section.

Example instruction:

"Divide the high-level summary into five sections:

1. 📝 Description — Summarize the main change in 50–60 words, explaining what was done.
2. 📓 References — List relevant issues, discussions, documentation, or related PRs.
3. 📦 Dependencies & Requirements — Mention any new/updated dependencies, environment variable changes, or configuration updates.
4. 📊 Contributor Summary — Include a Markdown table showing contributions:
   | Contributor | Lines Added | Lines Removed | Files Changed |
5. ✔️ Additional Notes — Add any extra reviewer context.
   Keep each section concise (under 200 words) and use bullet or numbered lists for clarity."

Note: This feature is currently in beta for Pro-tier users, and pricing will be announced later.
