Use WiFi stack for networking

 This project depends on [`Arduino_SNMP`](https://github.com/patricklaf/SNMP).
 
 
+### Quirks
+
+Despite communication being over Ethernet, the project makes use of the ESP32 Wifi stack, hence some
+references to Wifi here and there (eg. `WiFiUdp`).
+
+
 ### Installation
 Either use the Arduino IDE and use its library manager to find the SNMP library, or use `arduino-cli`:
