Ethernet is not a device, it is software protocol. There is hardware to implement the protocol, e.g. NICs, switches, hubs, etc.
To connect embedded Ethernet to a device, you typically use an Ethernet controller or module that interfaces with the device's microcontroller via protocols like SPI or UART. First, ensure the microcontroller has the necessary GPIO pins for the Ethernet module. Then, configure the Ethernet settings (IP address, subnet mask, etc.) in the device's firmware. Finally, establish a physical connection using an Ethernet cable to connect the module to a network switch or router.

To connect your device to the internet using an Ethernet cable adapter for the wall, simply plug one end of the Ethernet cable into the adapter and the other end into your device's Ethernet port. This will establish a wired connection to the internet through the wall adapter.
Ethernet is bi-directional; it both transmits and receives data.

Arpa encapsulation must be used to enable Ethernet II frame type on your Ethernet.
a repeater
To test an Ethernet port, you can use a known working Ethernet cable and connect it to a device with a functioning Ethernet port. Check if the device recognizes the connection and can access the network. You can also use a network testing tool to check for connectivity and data transfer speeds.
