Detailed Description

Network device transmission queue interface.

Introspection did not find any typical Config paths.

This interface is used by the traffic control layer and by the aggregated device to access the transmission queues of the device. Additionally, through this interface, traffic control aware netdevices can:

set the number of transmission queues
set the method used (by upper layers) to determine the transmission queue in which the netdevice would enqueue a given packet NetDevice helpers create this interface and aggregate it to the device.

Attributes

NTxQueues: The number of device transmission queues
- Set with class: ns3::UintegerValue
- Underlying type: uint16_t 1:65535
- Initial value: 1
- Flags: construct read

No TraceSources are defined for this type.
Size of this type is 88 bytes (on a 64-bit architecture).
