Removing that part of the code should have no effect on the networking working 
or not.

That you get a result of 0.00 suggests the control connection is established 
between the board and the target system, but not the data connection.

What happens when you run netserver on the board and netperf on the linux system?

You might try enabling debug output in netperf - it would be good to see that 
the control connection is OK.  Might also take a system call trace to see that 
netperf is using the "right" IP addresses and ports and such.
