[LARTC] tc patched doesn't work with WFQ

Hi,

I was searching for few days in this mailing list but I didn't find how to solve my tc problem.
Feel free to ask me more details if you think there are relevant.

I'm using a Gentoo 2.4.32-gentoo-r2 and I'm trying to test a *weighted fair queuing* (WFQ)
implementation. See http://home.sch.bme.hu/~tusi/wfq/

I patched the kernel and loaded the sch_wfq module, I patched iproute2/tc and compile everything.
I tried the command

- ------------
# tc qdisc add dev eth0 root handle 1:0 wfq 1 ifspped 12500000
Unknown qdisc "wfq", hence option "1" is unparsable
#
- ------------

the problem is that tc doesn't recognize the qdisc wfq.
I tried to compile wfq as a module and into the kernel, both gave the same error message.

I also check this :

- ------------
# tc qdisc add dev eth0 root handle 1:0 cbq bandwidth 100Mbit avpkt 1000 mpu 64
- ------------

and tc works fine !!!

I really don't understand what am I doing wrong????

Everything needed in the kernel is loaded, and when I compile *sch_wfq* as a module,
I retry the tc command above (the first one). I had the error mesage,
and I see (with lsmod) that the module is "unused".
Well, it's pretty obvious that tc didn't use it.

Any help is needed, thank you in advance.

I think you will find that the patch to iproute2 is too old.  The
iproute used to create it has a date in year 2000 and iproute2 has
changed substantially since then.

I suggest you contact the author and request a new patch.

Thank you so MUCH!!!

I sent him email but no reply so far. I think I'm going to do it by myself.

Thank you again.

Also, since tc supports shared libraries for additional queue disciplines. You could
set it up to build a .so and put in /usr/lib/tc. Then you wouldn't need to rebuild
all of iproute2.
