hi all i am a new commer of linux community. i want to how does skb->tcindex value change exactly. it confused me indeed. i have a script reads: (1) tc qdisc add dev eth0 root handle 1:0 dsmark indices 64 default_index 0x161 set_tc_index (2) tc filter add dev eth0 parent 1:0 protocol all prio 1 tcindex mask 0xfc shift 2 pass_on (3) tc filter add dev eth0 parent 1:0 prio 1 handle 0x0a tcindex classid 1:111 (4) tc filter add dev eth0 parent 2:0 protocol all prio 1 tcindex mask 0xf0 shift 4 pass_on (5) tc filter add dev eth0 parent 2:...

...d to map directly to the hardware queue, since we''ve already classified them correctly. However by the time it gets into the driver nothing in the skb seems to be usefully set to allow this. I''m looking at skb->priority, skb->dst->tclassid, skb->tc_classid, skb->tc_index, skb->tc_verd (okay, that was reaching). If I ping with different QoS bits which I''m assigning to different htb flows, I see (these are my debugging messages in the driver): ~$ ping -Q 0x10 172.29.50.230 kernel: outpkt: priority:06 tclassid:0x0 tc_classid:0x0 tc_index:0x0 tc_verd:0x...

I ''ve been trynig for a long time now to make HTB and GRED to work togethen. The problem beeing that GRED doesn''t use handles (instead it uses DP:1 DP:2 etc) i can not preperly filter traffic to them. Tomas Graf suggested to use the tc_index index of u32 classifier so dear Sant .. i am currently with the following scripts that works! But when i try to add an HTB before the GRED, everything goes to hell. tc qdisc add dev $Dev handle 1:0 root dsmark indices 16 set_tc_index tc filter add dev $Dev parent 1:0 protocol ip prio 1 tcinde...

Hi, I am tring to setup AF on my router using GRED/HTB. I plan to mark and set the DSCP with iptables and the ingress qdisc to set the tc_index for the proper GRED vq(1-12). My question is: Is there a way to allow for priority between the af classes and within the af classes? also would it be possible to to the following: HTB(6Mb) | GRED(1)grio HTB1 (af1) (1MB) GRED(1-3)grio | GRED(2)grio HTB2(af2) (1MB) GRED(1...

Hello, We know, VQs are used in Gred to offer different schedulers, in order to make clear what the VQs are, I have read the sch_gred.c in net/sched/. In the function gred_enqueue(), at first it will find the VQ(q) according to the lower four bits of the skb->tc_index, then some parameters of the q is modified, such as q->packetsin and q->bytesin. At last the packet was put into the physical Queue using __skb_queue_tail(). When dequeue the packet, only the function __skb_dequeue() is called, and the VQ parameters are modified. Then the packets from all VQ...

...prio 100 handle 151 tcindex classid 10:100 The first 4 commands were executed successfully , but the last line which use tcindex always get the wrong echo as: "Unknown filter "tcindex", hence option "classid" is unparsable" , I''m sure I''ve check the tc_index item in the Linux kernel configuration (I use linux2.4.0). Is there anyone would do me a favor to tell me why this does not work? Thanks a lot. James Shen

Hi, I am trying to implement a simple scaled-down version of the AF traffic class type. As such I basically want to remark non-conforming AF11 packets to AF13.

tl;dr ===== This patchset adds a single bit to the skb to indicate that a packet encountered a layer 2 miss in the bridge and extends flower to match on this metadata. This is required for non-DF (Designated Forwarder) filtering in EVPN multi-homing which prevents decapsulated BUM packets from being forwarded multiple times to the same multi-homed host.

Greetings from a newbie! (Well, to this list anyway) I''m having a problem and I hope someone here might be able to help... I am strongly expecting an answer along the lines of "upgrade to v2.4.x", but I would REALLY preffer to avoid that for now... The setup: "Home brewed" v2.2.24 (will patch to v2.2.25 later today) with the DS8 patch applied. Currently

The HTB scheduler code is a mess, this patch set does some basic house cleaning. The first four should cause no code change, but the last two need more testing. -- Stephen Hemminger <shemminger@osdl.org> "And in the Packet there writ down that doome" - To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to
