[netperf-talk] netperf4 doesn't do TCP_NODELAY

[Rick Jones]

In the unlikely event that you are using netperf4 and trying to set TCP_NODELAY 
with the "no_delay" socket_args attribute you should know that at present the 
netperf4 sources are missing the check for that property and so will never set 
TCP_NODELAY on a socket.

Once I can get my svn troubles sorted (no idea when) I'll add a fix.  Meanwhile, 
here is a diff:

hpcpc109:~/netperf4_trunk# svn diff src/nettest_bsd.c
