2009-05-06net-sched: fix bfifo default limitPatrick McHardy1-1/+1
When no limit is given, the bfifo uses a default of tx_queue_len * mtu. Packets handled by qdiscs include the link layer header, so this should be taken into account, similar to what other qdiscs do.

2008-11-13pkt_sched: Remove qdisc->ops->requeue() etc.Jarek Poplawski1-2/+0
After implementing qdisc->ops->peek() and changing sch_netem into classless qdisc there are no more qdisc->ops->requeue() users. This patch removes this method with its wrappers (qdisc_requeue()), and also unused qdisc->requeue structure. There are a few minor fixes of warnings (htb_enqueue()) and comments btw. The idea to kill ->requeue() and a similar patch were first developed by David S. Miller. Signed-off-by: Jarek Poplawski <jarkao2@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2008-10-31pkt_sched: Add ->peek() methods for fifo, prio and SFQ qdiscs.Patrick McHardy1-0/+2
From: Patrick McHardy <kaber@trash.net> Just as a demonstration how easy adding a peek operation to the work-conserving qdiscs actually is. It doesn't need to keep or change any internal state in many cases thanks to the guarantee that the packet will either be dequeued or, if another packet arrives, the upper qdisc will immediately ->peek again to reevaluate the state. (This is only slightly modified Patrick's patch.) Signed-off-by: Jarek Poplawski <jarkao2@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2008-07-08pkt_sched: Remove 'dev' member of struct Qdisc.David S. Miller1-3/+3
It can be obtained via the netdev_queue. So create a helper routine, qdisc_dev(), to make the transformations nicer looking. Now, qdisc_alloc() now no longer needs a net_device pointer argument. Signed-off-by: David S. Miller <davem@davemloft.net>
2008-07-08netdev: Create netdev_queue abstraction.David S. Miller1-1/+2
A netdev_queue is an entity managed by a qdisc. Currently there is one RX and one TX queue, and a netdev_queue merely contains a backpointer to the net_device. The Qdisc struct is augmented with a netdev_queue pointer as well. Eventually the 'dev' Qdisc member will go away and we will have the resulting hierarchy: net_device --> netdev_queue --> Qdisc Also, qdisc_alloc() and qdisc_create_dflt() now take a netdev_queue pointer argument.

2008-01-28[NET_SCHED]: Convert packet schedulers from rtnetlink to new netlink APIPatrick McHardy1-5/+5
Convert packet schedulers to use the netlink API. Unfortunately a gradual conversion is not possible without breaking compilation in the middle or adding lots of casts, so this patch converts them all in one step. The patch has been mostly generated automatically with some minor edits to at least allow seperate conversion of classifiers and actions.

2008-01-28[NET]: Move Qdisc_class_ops and Qdisc_ops in appropriate sections.Eric Dumazet1-2/+2
Qdisc_class_ops are const, and Qdisc_ops are mostly read. Using "const" and "__read_mostly" qualifiers helps to reduce false sharing. Signed-off-by: Eric Dumazet <dada1@cosmosbay.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2005-06-18[PKT_SCHED]: Cleanup fifo qdisc and remove unnecessary codeThomas Graf1-38/+12
Removes the skb trimming code which is not needed since we never touch the skb upon failure. Removes unnecessary includes, initializers, and simplifies the code a bit. Signed-off-by: Thomas Graf <tgraf@suug.ch> Signed-off-by: David S. Miller <davem@davemloft.net>
2005-06-18[PKT_SCHED]: Transform fifo qdisc to use generic queue management interfaceThomas Graf1-88/+14
The simplicity of the fifo qdisc allows several qdisc operations to be redirected to the relevant queue management function directly. Saves a lot of code lines and gives the pfifo a byte based backlog. Signed-off-by: Thomas Graf <tgraf@suug.ch> Signed-off-by: David S. Miller <davem@davemloft.net>
2005-04-16Linux-2.6.12-rc2Linus Torvalds1-0/+212
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
