OLSR Implementation for XORP

 *
 * By Ying Ge:
 * 1. Change the OLSR packet format and message processing procedure based 
 *    on the OLSR RFC.
 * 2. Add support of multiple interfaces to OLSR, including MID message 
 *    creating and processing procedure as specified in the OLSR RFC.
 * 3. Add QoS Support to OLSR
 *
 * By Maoyu Wang:
 * 1. Ported OLSR from IPv4 to IPv6.
 * 2. Added the Host and Network Association (HNA) functionality into OLSR.
 * 3. Added the default gateway functionality into OLSR by extending the HNA 
 *    message usage. The default gateway functionality supported the mobility
 *	  by cooperating with Mobile IPv6 for a mobile node as well as supported 
 * 	  Internet access for MANET nodes.
