TCP agent always set ssthresh_ = int(wnd_).

Hi,

The reset() method of class TCPAgent will set ssthresh_ = int(wnd_), I
think
this is not necessary. Maybe someone(for example, I) want to set wnd_
(window_ in TCL, the receive window) a different value from ssthresh_
(ssthresh_ in TCL, slow start threshold), and I think in real TCP, these
two variable are not always the
same.
