I'm happy to see C code, but this implementation still doesn't address
any of my comments I posted in the
Re: [PATCH v2] rtl83xx-poe: add package
https://patchwork.ozlabs.org/project/openwrt/patch/20210313165419.10713-1-bjorn@mork.no/#2666485

I strongly believe we need a more generic solution. A tiny framework
with generic PoE imlementation and then rtl83xx support on top of that.
