How stonemaguire/nativeethernet works

NativeEthernet is a Teensy 4.1 networking library that replaces the Arduino Ethernet API, backed by the FNET stack. A sketch configures Ethernet and then uses TCP client/server or UDP APIs; hostname-based UDP destinations use DNS resolution, and the library also exposes mDNS service registration. The excerpts show socket operations delegated to a socket layer and FNET calls, but do not establish every initialization or dispatch relationship, so those links are omitted.
