The docs have been updated. max_len is libfuzzer specific, new way is fuzzer agnostic. Docs: https://chromium.googlesource.com/chromium/src/+/master/testing/libfuzzer/getting_started.md#improving-your-fuzz-target Bug: chromium:895082 Test: flexfec_sender_fuzzer input size still converges at <=200 after running locally for 5-10 minutes.
