 * PROBLEM DESCRIPTION: MPRoute gets error "DTCMPR7828I Error   *
 *                      adding/deleting/changing stack rte"     *
 *                      when trying to delete TCP/IP stack      *
 *                      routes.                                 *

 * RECOMMENDATION: APPLY PTF                                    *
 ****************************************************************
 When MPROUTE sends a command to the stack to add or delete a
 route, the stack calls FindRoute to search the tree and
 determine if the route is in the tree.  FindRoute is not
 finding the correct routing entry, so additions and deletions
 may fail.
 
 PROBLEM CONCLUSION:
 When the stack has multiple routing entries to the same
 destination with different subnetmasks, the routing tree
 order can be corrupted when deleting routes.  TreeDeleteNode
 was changed to maintain the correct tree order when deleting
 routing nodes. FindRoute was also changed to keep track of
 the most specific route found so far and continue searching
 as long as the subsequent nodes have a better match.  This
 ensures that FindRoute finds the best route.
