Not sure about this. The point of l3fwd is to make it as simple
an application as possible to help users.
Given that drivers can now supply default values for thresholds, I think
the l3fwd sample should get rid of all the special descriptor values it
is setting. Then if the values are not right for best performance that should
be pushed back to the driver writer to fix.
