Yes, that would probably be a good idea; and also agreement on the values would be a good idea ;) the current mapping I put in is taken from netperf, which in turn cites an RFC. But it's different from the irtt man page, I guess because of the difference in number of bits...

Not sure the Go API actually only sets the six bits, though?
