netperf_stress is a 2 machine test (server/client) that measures the performance
of various network attributes. This test will cycle through the various types
of supported tests and streams, and will take about 1 hour to run. 
You can adjust the streams by changing the values of the streams list in the
run function.

Arguments to run_test:

test          - the list of valid netperf tests that can be run
                This currently is:
                  TCP_STREAM, TCP_SENDFILE, TCP_RR, TCP_CRR, UDP_STREAM, UDP_RR
test_time     - Specifies how long each iteration of the test should run for.
stream_list   - A list containing the number of streams to run the test for. If
                the list is [1,10,100] then the test will run 3 times. If
                bidirectional is set then there will be the specified number of
                bidirectional streams.
