+ * For each packet leaving a VM, the system searches that VM's routing table for

+ * tie, the system selects the Route with the smallest priority value. If there
+ * is still a tie, it uses the layer three and four packet headers to select
+ * just one of the remaining matching Routes. The packet is then forwarded as
+ * specified by the next_hop field of the winning Route -- either to another VM
+ * destination, a VM gateway or a GCE operated gateway. Packets that do not
