Subject: [LARTC] Creating new qdisc?
Date: Wed, 20 Nov 2002 08:49:42 +0000	[thread overview]
Message-ID: <marc-lartc-103778226518540@msgid-missing> (raw)

Hi all,

I am trying to implement a new qdisc, but I'm having trouble. Here's what I've 
done:

I've copied the TBF source into a new file, and modified it to represent my new 
qdisc. Then added it to the default qdiscs in the Makefile. I modified the 
header files include/net/pkt_sched.h and include/linux/pkt_sched.h to reflect 
my new qdisc. The kernel compiles and runs fine. (using UML)

Then I went ahead and modified tc to include support for the qdisc, once again 
using the exsisting code as a basis. It compiles and runs fine.

When I try to insert the EXISTING TBF, it works great. When I call tc with the 
same arguments, but for my new qdisc it returns (i gather 
infamous): "RT_NETLINK: Invalid argument". I didn't change the actual 
parameters or code for the qdisc, so it is still identical to the default TBF. 
So the parameters I pass *should* be fine.

I'm wondering if I left something out that the kernel requires to recognize the 
new qdisc.

Thanks in advance.
Yell if you need more code/information.
