There's no way this is legitimate, that commit cannot possibly affect the
performance of netperf. I wouldn't bother to spend any time investigating
this.

One assumption could be that netperf was setting this knob
internally and ignoring the result of it (error/success), but
that we might need to look up in netperf source to confirm.

Confirmed netperf-2.4.5 doesn't do this.

Ok, thanks for checking, then I fully agree with you.
