When running the `quinn-udp` `ecn_*` unit tests `sendmsg` fails with: ``` 2024-08-22T14:41:30.636494Z WARN quinn_udp: sendmsg error: Os { code: 22, kind: InvalidInput, message: "Invalid argument" }, Transmit: { destination: 127.0.0.1:50196,...

#### What happened We attempted switching Firefox Nightly to use `quinn-udp` for QUIC UDP I/O by default recently, though we had to roll back due to an error on Android...

Previously `quinn*` would provide the `log` feature to log events via `log` if no `tracing` subscriber exists. Later https://github.com/quinn-rs/quinn/pull/1923 allowed `quinn-udp` to log via `log` directly, making `tracing` an optional...
