This is already fixed in netperf2 SVN trunk. See:

Because some little endian ARM machines use mixed endian IEEE double floating
point format and the process of passing doubles back and forth between host
and client corrupts those doubles.

It has nothing to do with ethernet config in thise case.  This problem depends
on what type of ARM machine you are running netperf2.  My guess is that you
have a little endian ARM machine with mixed endian doubles and are using
netperf2 2.4.1 or earlier.

Try latest netperf2 SVN trunk, it should fix the problem.
