Unfortunately these aren't supported by libuv directly, so we need to implement our own separate system. It doesn't need to be particularly scalable as the expected use-case is to send and receive ethernet frames.
The server will listen on a Unix domain socket and receive connected SOCK_DGRAM sockets which will have ethernet frames on them.
