| eth_device decorator is used to implement an api to ethernet devices. | |||
| When eth_device decorator is used it adds two parameters to any function (ip and port) | |||
| #Definition | |||

| def enable_rf() | |||
| cmd = "xxxxx" | |||
| payload = "xxxxxx" | |||

| #How to call this function: | |||
