The aim of the QosTag is to provide means for an Application to specify the TID which will be used by a QoS-aware WifiMac for a given traffic flow.
Doxygen introspection did not find any typical Config paths.
Note that the current QosTag class was designed to be completely mac/wifi specific without any attempt at being generic.
No TraceSources are defined for this type.

Here is the call graph for this function:| void ns3::QosTag::SetTid | ( | uint8_t | tid | ) |
Set the TID to the given value.
This assumes that the application is aware of the QoS support provided by the MAC layer, and is therefore able to set the correct TID.
| tid | the value of the TID to set |

| void ns3::QosTag::SetUserPriority | ( | UserPriority | up | ) |
Set the TID to the value that corresponds to the requested UserPriority.
Note that, since the mapping of UserPriority to TID is defined for EDCA only, you should call this method only when EDCA is used. When using HDCA, QosTag(uint8_t tid) should be used instead.
