Back2Back: update default params
Update the default duration of a back to back test to be 2 seconds which is the minimum recommended by RFC2544, and update the Trials to be 50, which is also the default value specified by the RFC. This patch also fixes the tcl script to allow for the minimum framesize to be sent from the traffic gen.

If the number of received frames equals the number of frames that were
transmitted, the burst size should be increased and traffic is sent to
the DUT again. The value measured is the back-to-back value, that is the

The following are the metrics collected for this test:
- - The back-to-back value, which is the the number of frames in the
- longest burst that the DUT will handle without the loss of any
- frames.
+ - The average back-to-back value across the trials, which is

+ handle without the loss of any frames.
- CPU and memory utilization may also be collected as part of this
test, to determine the vSwitch's performance footprint on the system.
