Traffic will begin flowing through each queue if your base device has either

the default simple_tx_hash or a custom netdev->select_queue() defined.



The behavior of tc filters remains the same.

The behavior of tc filters remains the same.  However a new tc action,

skbedit, has been added.  Assuming you wanted to route all traffic to a

specific host, for example 192.168.0.3, though a specific queue you could use

this action and establish a filter such as:



tc filter add dev eth0 parent 1: protocol ip prio 1 u32 \

	match ip dst 192.168.0.3 \

	action skbedit queue_mapping 3
