The value of tRPAdminPSDefaultActionNextHopSelf specifies
the next-hop-self on the route. Next-hop-self cannot be set
to 'true' at the same time as setting next-hop object
tRPAdminPSDefActInetNextHop to a valid IP address.
Setting tRPAdminPSDefaultActionNextHopSelf to 'true' will
reset tRPAdminPSDefActInetNextHop object to disable.
