Just as a datapoint, I also had a lot of "fun" with the gmac0 on my qnap ts433 today. Cable connection was detected but dhcp did not get an IP address. In the end I realized that the vccio4 supply was 1.8V but the pmu-io-domains were not enabled, so the soc thought it got 3.3V After enabling pmu-io-domains [0], I now get networking on that port.
