step:
1. 0x0475 has been set to 0x2000 or 0x3000;
2. and there is no power down or reset;
3.swap the two wires of the MDI and reconnect;
4.wait a few seconds;
5.read register 1, return 0x65, it means link up;
question:
After exchanging the two wires of MDI many times, it can still link up, isn’t the polarity adaptation disabled? When the line sequence is incorrect, shouldn’t it not be able to link up?
