HCoS: GRE tunnel interface output queues

You can manage output queuing of traffic entering GRE tunnel interfaces hosted on MPC5E line cards in routers. Support for the output-traffic-control-profile configuration statement, which applies an output traffic scheduling and shaping profile to the interface, is extended to GRE tunnel physical and logical interfaces. Support for the output-traffic-control-profile-remaining configuration statement, which applies an output traffic scheduling and shaping profile for remaining traffic to the interface, is extended to GRE tunnel physical interfaces.
