From a42debaf18fd9b12220ccdc78db74f4852aa1a4f Mon Sep 17 00:00:00 2001
From: Ryan Izard <ryan.izard@bigswitch.com>
Date: Fri, 15 Jul 2016 09:43:25 -0400
Subject: [PATCH] compute() has been optimized and all old code is gone. We no
longer need to compute trees for each cluster. Furthermore, the computation
of broadcast ports has been streamlined. Other routing/topology refactoring
has been done as well.
