This small series gets my hardware into a working state. The key points are to make sure we don't force the link and that we ask the MAC for the link status. I also have updated my dts to say `phy-mode = "1000base-x";` and `managed = "in-band-status";`
I've included patch #4 in this series but I don't have anything to test it on. It's just a guess based on the datasheets. I'd suggest applying patch 1, 2 & 3 and leaving 4 for the mailing list archives.
