Note:
* [^1]: LEDs are found by just plugin a RJ45 connector and see with cmd `gpio` the status change. But the bit pattern for port 1,2 are diffrent from port 3,4.
* [^2]: Only on the unmanaged verions are `R10` and `R268` placed. But the very low pull-down resistor `R10` & `R262` prevent to SOC to drive does pins. A mod is needed.
* [3]: GPIO54 is used for the reset-button. `T-R85` is placed.

Chip can deliver up to 4A and the sweetspot is at 1A.
So higher power SFP-modules should work.
