UPDATE: The Code comes with a port of the [uIP](https://github.com/adamdunkels/uip)
TCP/IP stack and includes a minimal web-server that can be used to work with the switch,
so if you use a patch-clamp for updating the firmware (~3 USD/EUR), you can try this
out without the need to solder anything. See the instructions below.
Note that updating the firmware of a managed switch with the images created in this
project will not work, because it is currently unknown how to generate the require
checksum, see this
[issue](https://github.com/up-n-atom/SWTG118AS/issues/4).
