I would like to send data from my computer to my Nucleo f7567zg board with ethernet.

[TRoza.1]

I didn't find a good tutorial or a legit example code to initialize the ethernet protocol. My project use UART communication at the moment but I need the ethernet. Is there anybody who could help me?

Thanks a lot!

There are a bunch of projects here using LwIP (over ethernet):

Using raw ethernet packets is not a common application.
