I've got those series applied, albeit locally, since they're not ready,
but I cannot get the Ethernet to work properly on my board.
I boot all of my dev boards w/ tftp, and the visionfive2 is no exception.
The fact that I am getting to the kernel in the first place means the
ethernet is working in the factory supplied U-Boot [1].

However, in Linux this ethernet port does not appear to work at all.
The other ethernet port is functional in Linux, but not in the factory
supplied U-Boot.

Is this a known issue? If it's not, I'll post the logs somewhere for
you. In case it is relevant, my board is a v1.2a.

Thanks,
Conor.
