Hey there Borromini,

I added some additional translation to realtek-poe -d, and I'm noticing that I get some errors from the MCU. I'm wondering whether this is related to the inability of realtek-poe to bring ports actually up?

:
TX -> 0x1a 0x09 0x03 0x01 0xff 0xff 0xff 0xff 0xff 0xff 0xff 0x20
Set port priority 
RX -> 0x1a 0x09 0x03 0x00 0xff 0xff 0xff 0xff 0xff 0xff 0xff 0x1f
Set port priority 
TX -> 0x1c 0x0a 0x03 0x01 0xff 0xff 0xff 0xff 0xff 0xff 0xff 0x23
Set port power-up mode
