Ethernet Shield support

[mattrob33]

I'm trying to use the Ethernet Shield rev2 hardware (and Ethernet library) with this. Is this supported already or is there a straightforward way to support it? There is an existing w5500 driver crate already, but I'm not sure if it's compatible with this project.

Right now I do not know if anyone ever attempted this. For sure I haven't seen any code so far. That doesn't mean that it won't work. If the w5500 driver uses embedded-hal, there is a good chance that you can connect it to avr-hal with ease. Let me know how it goes. If you hit any problems, me or someone else here might also be able to help, so do post them as well.
