+ * @file listenerSet.h
+ * @brief A listener set is unique on (EncapType, localAddress)
+ *
+ * Keeps track of all the running listeners.  The set is unique on the
+ * encapsulation type and the local address.  For example, with TCP
+ * encapsulation and local address 127.0.0.1 or Ethernet encapsulation and MAC
+ * address 00:11:22:33:44:55.
+ *
+ * NOTE: This does not allow multiple EtherType on the same interface because
+ * the Address for a LINK address does not include an EtherType.
