[fedora-arm] Re: Wandboard Quad RevD1 has no Ethernet in Fedora F31?

I have a Wandboard Quad B1 and ethernet works, I know others have other revs.

I'm not sure the context of where that is fixed as I wasn't sure of
where it was fixed. I suspect it was maybe in their downstream kernel
fork. We only use upstream/mainline kernels.

So for the vast majority of device support we rely on things being
upstream, both in the linux kernel and in firmware like U-Boot. We
don't have the resources to upstream everything and follow downstream
problems/fixes for every random device.

Looking at the upstream changes for the D1 specific rev I see the
following since the D1 one support landed, nothing about network

So looking quickly at the post you mention, and looking at the
upstream kernel commits back to when D1 support landed to 5.7-rc1
there doesn't look to be anything network related:
