Hi all, I'm working within an application which creates packets and sends them. To accomplish this I use the dev_queue_xmit function. At a fist stage, everything runs OK, but I would like also to giv

You can set skb->priority to values between 0 and 15 (see include/linux/pkt_sched.h) What actually happens depends on the queueing discipline that is set for the interface. The default one uses a 3 w

This is one of the reasons for drivers to keep their Tx queues to a reasonable length. Two years ago an almost-always-sufficient Tx queue length was between 6 and 10, so most of my bus-master drivers

Donald, The Tulip, for example, can have its DMA buffers stashed in a linked list instead of a ring structure. Maybe not the most efficient scheme but could you could play with priority queueing stru

Keep thinking about loud... I was thinking that a linked list would be more flexible and potentially more optimal, but checking that out is 2.5.x material for me :)

.. Not if you want to work with different Tulip chip types! The driver sets up the descriptors as both a ring and a linked list. That way it works both with chips that only implement chained mode, an

The data size frequently isn't a better metric: - On a busy half duplex network your outbound queue delay is a primarily function of the number of packets, not the size of those packets. - Is it real

Actually, this is not re-ordering per-se. This would be done _per-flow_ and not with packets within the same flow. i.e certain flows are more important than others and would skip FIFO queue rules. B
