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:
