I recognize that standard FOU configurations do not typically have multiple listeners on the same port (returning -EADDRINUSE), so this primarily affects multi-socket/SO_REUSEPORT encapsulation scenarios. If you consider this an edge case not worth touching, I am completely fine dropping the patch. Thanks, Mariano
