To run and analyze the results, do the following :

0. Modify iperc.c and iperf.s to give correct device name and IP
   address
1. Run iperf.c (iperf.s on server) on unmodified net-2.6.23 kernel, org
   result file is created.
2. Run iperf.c (iperf.s on server) on patched net-2.6.23 kernel, new
   result file is created.
3. Run 'compare_perf <org_result_file> <new_result_file>' to compare the
   two test runs.
