PlatformIO cannot find Ethernet.h

Hello !

I am trying to implement an Ethernet connection instead of an WiFi connection.

The problem is that PlatformIO can't even find Ethernet.h.

This is how I start a WiFi connection in STA Mode right now:

       if(!WiFi.config(local_IP_STA, gateway_STA, subnet_STA, local_IP_STA, primaryDNS)) {
         logOutput((String)"Couldn't configure STATIC IP ! Starting DHCP IP !");
       }
       delay(50);
       WiFi.begin(x[0].c_str(),x[1].c_str());

What is the equivalent for the above code when using Ethernet ?

Also, can Ethernet be used in AP Mode ?

Thank you !
