wrong "socket TOS:" output when -d 10 is used

[O-ring]

Hello everyone,

I noticed that the output of the fields (when the -d 10 debug option is used):

Local socket TOS:
Remote socket TOS:

is not always correct. I have done the whole sequence of cases and this is the output.
However the traffic is generated with the correct value in the "tos" field.

This is netperf 2.7.0 compiled from sources with the following options:
configure --prefix=/usr --enable-demo --enable-histogram
