[gentoo-user] [OT] traffic shaping

[Uwe Thiem]

Hi folks,

I am struggling with traffic shaping. I have ironed out most rough things but 
are stuck with one remaining issue.

It happens as soon as I enter any one of the following lines:

tc filter add dev eth2 parent 1: prio 2 handle 1 fw flowid 1:20
tc filter add dev eth2 parent 1: protocol ip prio 2 handle 1 fw flowid 1:20
tc filter add dev eth2 parent 1: prio 2 handle 1 fw classid 1:20
tc filter add dev eth2 parent 1: protocol ip prio 2 handle 1 fw classid 1:20

I then get the error message:
RTNETLINK answers: Invalid argument
We have an error talking to the kernel

Prior experience suggests that a module is missing or not loaded. The question 
is: Which one? Or am I completely wrong in my assumption?

Any experts here to lend a brain cell? ;-)

Uwe

Did you compile "QoS and/or fair queuing" support into the kernel
(i.e., not the "traffic shaping device" which is in the device
section)? It should then load modules automatically (well, if
configured in the kernel, that is).

Hm, and you _did_ set up the qdiscs and classes first? OTOH, and I
don't know for sure if that's needed before configuring the filters.

I do believe that the q-classes are needed.
