The basic registers look correct, but some of the registers appear to be in decimal format. Could you double check these and provide the values in hexadecimal format?

The connections to the transformer and connector are not shown. Could you please share this portion of the schematic?

What is the link partner in your testing? Is the PHY on the other end of the cable also seeing errors?
