I have hardware that can classify incoming IP-packets L2-L4, and on the DS field. This classification allows me to know what outgoing NIC the packets should end up on, but I still want normal QOS functionality for this traffic, so I can't push the packets across while staying in the driver. Is there any good way of making use of the availability of a TCAM-alike packet rule classifier while still having the kernel sort/drop/queue the packets according to various QOS-settings (with no limitation on what king of policy that can be used for a certain flow) before they end up in the outgoind NIC? The aim for this application is to get good packet rate in a system that doesn't have much CPU to spare. /Daniel
