[ns] TCP receiver window_ sizes

[Karen Wang]

Hi,

In tcp.cc, the window_ parameter (or wnd_) sets the receiver window size,
and thus serves as a limit to how much the sender can output onto the link.

However, if you look at tcp-sink.cc, is it true that the MWS macro limits 
the true receiver window size?  (So that if someone sets Tcp window_ to be
2000 packets, when MWS is set to only 1000 packets, say, then the simulated
behavior of the person's Tcp connection may not be what he/she originally
intended?)

Thanks,
Karen
