Create a mac helper in a default working state.

void ns3::QosWifiMacHelper::SetBlockAckInactivityTimeoutForAc	(	enum AcIndex	ac,
		uint16_t	timeout
	)

Sets value of block ack inactivity timeout for a specific access class. timeout represents number of blocks of 1024 microseconds. When this timer expires the relative block ack agreement is teared down. Timer is reset in an recipient station every time that a block ack request or a MPDU with ack policy BLOCK ACK is received. Timer is reset in a originator station every time that a block ack frame is received.

Parameters:

	ac	access category for which we are setting block ack threshold. Possibilities are: AC_BK, AC_BE, AC_VI, AC_VO.
	timeout	number of block of 1024 microseconds.

void ns3::QosWifiMacHelper::SetBlockAckThresholdForAc	(	enum AcIndex	ac,
		uint8_t	threshold
	)

This method sets value of block ack threshold for a specific access class. If number of packets in the respective queue reaches this value block ack mechanism is used.

Parameters:

	ac	access category for which we are setting block ack threshold. Possibilities are: AC_BK, AC_BE, AC_VI, AC_VO.
	threshold	the threshold (number of packets)

void ns3::QosWifiMacHelper::SetMsduAggregatorForAc	(	AcIndex	ac,
		std::string	type,
		std::string	n0 = "",
		const AttributeValue &	v0 = EmptyAttributeValue(),
		std::string	n1 = "",
		const AttributeValue &	v1 = EmptyAttributeValue(),
		std::string	n2 = "",
		const AttributeValue &	v2 = EmptyAttributeValue(),
		std::string	n3 = "",
		const AttributeValue &	v3 = EmptyAttributeValue()
	)

Set the class, type and attributes for the Msdu aggregator

Parameters:

	ac	access category for which we are setting aggregator. Possibilities are: AC_BK, AC_BE, AC_VI, AC_VO.
	type	the type of ns3::MsduAggregator to create.
	n0	the name of the attribute to set
	v0	the value of the attribute to set
	n1	the name of the attribute to set
	v1	the value of the attribute to set
	n2	the name of the attribute to set
	v2	the value of the attribute to set
	n3	the name of the attribute to set
	v3	the value of the attribute to set

All the attributes specified in this method should exist in the requested aggregator.

void ns3::QosWifiMacHelper::SetType	(	std::string	type,
		std::string	n0 = "",
		const AttributeValue &	v0 = EmptyAttributeValue(),
		std::string	n1 = "",
		const AttributeValue &	v1 = EmptyAttributeValue(),
		std::string	n2 = "",
		const AttributeValue &	v2 = EmptyAttributeValue(),
		std::string	n3 = "",
		const AttributeValue &	v3 = EmptyAttributeValue(),
		std::string	n4 = "",
		const AttributeValue &	v4 = EmptyAttributeValue(),
		std::string	n5 = "",
		const AttributeValue &	v5 = EmptyAttributeValue(),
		std::string	n6 = "",
		const AttributeValue &	v6 = EmptyAttributeValue(),
		std::string	n7 = "",
		const AttributeValue &	v7 = EmptyAttributeValue()
	)

Set the underlying type of the MAC and its attributes.

Parameters:

	type	the type of ns3::WifiMac to create.
	n0	the name of the attribute to set
	v0	the value of the attribute to set
	n1	the name of the attribute to set
	v1	the value of the attribute to set
	n2	the name of the attribute to set
	v2	the value of the attribute to set
	n3	the name of the attribute to set
	v3	the value of the attribute to set
	n4	the name of the attribute to set
	v4	the value of the attribute to set
	n5	the name of the attribute to set
	v5	the value of the attribute to set
	n6	the name of the attribute to set
	v6	the value of the attribute to set
	n7	the name of the attribute to set
	v7	the value of the attribute to set

All the attributes specified in this method should exist in the requested mac.
