The parameter "newreno_changes_" is described on the man page. 
When "newreno_changes_" is set to 1, it changes the slow-start
behavior.  The default is for "newreno_changes_" to be set to 0.

>From the man page:

newreno_changes_

Set to zero for the default NewReno described in [7].  Set to 1
for additional NewReno algorithms as suggested in [10]; this includes
the estimation of the ssthresh parameter during slow-start.
