Namespaces
namespace	ns3
	Every class exported by the ns3 library is enclosed in the ns3 namespace.

Functions
uint8_t	ns3::GetTid (Ptr< const Packet > packet, const WifiMacHeader hdr)
	This function is useful to get traffic id of different packet types.
bool	ns3::operator< (AcIndex left, AcIndex right)
	Operator< overload returning true if the AC on the left has lower priority than the AC on the right.
bool	ns3::operator<= (AcIndex left, AcIndex right)
	Operator<= overload returning true if the AC on the left has lower or the same priority than the AC on the right.
bool	ns3::operator> (AcIndex left, AcIndex right)
	Operator> overload returning true if the AC on the left has higher priority than the AC on the right.
bool	ns3::operator>= (AcIndex left, AcIndex right)
	Operator>= overload returning true if the AC on the left has higher or the same priority than the AC on the right.
uint8_t	ns3::QosUtilsGetTidForPacket (Ptr< const Packet > packet)
	If a QoS tag is attached to the packet, returns a value < 8.
bool	ns3::QosUtilsIsOldPacket (uint16_t startingSeq, uint16_t seqNumber)
	This function checks if packet with sequence number seqNumber is an "old" packet.
uint32_t	ns3::QosUtilsMapSeqControlToUniqueInteger (uint16_t seqControl, uint16_t endSequence)
	Next function is useful to correctly sort buffered packets under block ack.
AcIndex	ns3::QosUtilsMapTidToAc (uint8_t tid)
	Maps TID (Traffic ID) to Access classes.
uint8_t	ns3::SelectQueueByDSField (Ptr< QueueItem > item)
	Determine the TX queue for a given packet.

Variables
const std::map< AcIndex, WifiAc >	ns3::wifiAcList
	Map containing the four ACs in increasing order of priority (according to Table 10-1 "UP-to-AC Mappings" of 802.11-2016)
