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 This interface is created and aggregated to a device by the traffic control layer when an Ipv{4,6}Interface is added to the device or a queue disc is installed on the device.

No Attributes are defined for this type.
No TraceSources are defined for this type.
Size of this type is 72 bytes (on a 64-bit architecture).
