 C xor is bitwise.

 I did a bit of scripting and found that the algorithm seems much more
 sensitive to port numbers than IP addresses. Not that iperf gives much
 control over those, it looks like the client port numbers are picked at
 random. As a result, I would expect to repeat this test on the same set
 of clients, say, hundreds of times, and maybe find a small number of
 cases where all interfaces are utilised.
