Hi Linda, that was actually a direct quote from Fred's document, so I
can't take credit for it ... however, all that it's saying is that
the congested queue set the CE bit (when ECT is set), per normal ECN
protocol.  It isn't saying anything new about the downstream nodes that
see CE has already been set.
