// TrafficScheduler (Class ID: #278 / 0x0116)
//	NOTE 1 - In [ITU-T G.984.4], this ME is called a traffic scheduler-G.
//
//	An instance of this ME represents a logical object that can control upstream GEM packets. A
//	traffic scheduler can accommodate GEM packets after a priority queue or other traffic scheduler
//	and transfer them towards the next traffic scheduler or T-CONT. Because T-CONTs and traffic
//	schedulers are created autonomously by the ONU, the ONU vendor predetermines the most complex
//	traffic handling model it is prepared to support; the OLT may use less than the ONU's full
//	capabilities, but cannot ask for more. See Appendix II for more details.
//
//	After the ONU creates instances of the T-CONT ME, it then autonomously creates instances of the
//	traffic scheduler ME.
//
//	Relationships
//		The traffic scheduler ME may be related to a T-CONT or other traffic schedulers through pointer
//		attributes.
//
//	Attributes
//		Managed Entity Id
//			This attribute uniquely identifies each instance of this ME. This 2-byte number indicates the
//			physical capability that realizes the traffic scheduler. The first byte is the slot ID of the
//			circuit pack with which this traffic scheduler is associated. For a traffic scheduler that is
//			not associated with a circuit pack, the first byte is 0xFF. The second byte is the traffic
//			scheduler id, assigned by the ONU itself. Traffic schedulers are numbered in ascending order
//			with the range 0..0xFF in each circuit pack or in the ONU core. (R) (mandatory) (2-bytes)
//
//		T_Cont Pointer
//			T-CONT pointer: This attribute points to the T-CONT ME instance associated with this traffic
//			scheduler. This pointer is used when this traffic scheduler is connected to the T-CONT directly;
//			It is null (0) otherwise. (R, W) (mandatory) (2 bytes)
//
//			NOTE 2 - This attribute is read-only unless otherwise specified by the QoS configuration
//			flexibility attribute of the ONU2-G ME. If flexible configuration is not supported, the ONU
//			should reject an attempt to set the TCONT pointer attribute with a parameter error result-reason
//			code.
//
//		Traffic Scheduler Pointer
//			This attribute points to another traffic scheduler ME instance that may serve this traffic
//			scheduler. This pointer is used when this traffic scheduler is connected to another traffic
//			scheduler; it is null (0) otherwise. (R) (mandatory) (2-bytes)
//
//		Policy
//			This attribute represents scheduling policy. Valid values include:
//
//			0	Null
//
//			1	Strict priority
//
//			2	WRR (weighted round robin)
//
//			The traffic scheduler derives priority or weight values for its tributary traffic schedulers or
//			priority queues from the tributary MEs themselves.
//
//			(R, W) (mandatory) (1 byte)
//
//			NOTE 3 - This attribute is read-only unless otherwise specified by the QoS configuration
//			flexibility attribute of the ONU2-G ME. If flexible configuration is not supported, the ONU
//			should reject an attempt to set the policy attribute with a parameter error result-reason code.
//
//		Priority_Weight
//			Priority/weight: This attribute represents the priority for strict priority scheduling or the
//			weight for WRR scheduling. This value is used by the next upstream ME, as indicated by the
//			T-CONT pointer attribute or traffic scheduler pointer attribute.
//
//			If the indicated pointer has policy-=-strict priority, this value is interpreted as a priority
//			(0 is the highest priority, 255 the lowest).
//
//			If the indicated pointer has policy-=-WRR, this value is interpreted as a weight. Higher values
//			receive more bandwidth.
//
//			Upon ME instantiation, the ONU sets this attribute to 0. (R,-W) (mandatory) (1-byte)
