patch

Christian Kreuzberger in ns-users group (https://groups.google.com/forum/#!topic/ns-3-users/VqNZogTqBMQ) proposed a number of enhancements to speedup IP L3 protocols in case of massive links in a node.

There is still room for some improvement, but it would require a bit more work. E.g., a node (switch) could want to limit the incoming L4 connections to a subset of ports. In this case the RouteInput could be changed to take advantage of this.

In the meantime, the attached patch effectively improves the simulation speed.
