Did someone here manage to get the builtin Ethernet phy in a CH32V307 running _apart_ from using the vendor SDK? I see is partial code in ch32-rs (buried in a PR), and probably with quite a bit of work ch32fun should be usable as well, but I have not found anything covering the whole chain yet and I have strong feelings about linking closed source binary blobs from vendor SDKs on something that plugs into TheInternet(TM)
