Ewe. The protocol is versioned now so we won’t see this going forward with newer versions (he said hopefully). I updated the faq with this info, thanks for testing!
I ran a few tests (on my Mac) to netperf-eu.bufferbloat.net with AQM off, which look good (more on that later). I do see an error code from fping, but I don’t see any problem with the results:
