Ok, I tried a kernel with CONFIG_NETLINK_DEV compiled in and the tc from
iproute2-2.4.7-now-ss020116-try.tar.gz but I still can't see any entries in
the class or filter list. After adding these rules:

------------< snip <------< snip <------< snip <------------
tc qdisc add dev eth0 root handle 1: cbq bandwidth 10Mbit cell 8 avpkt 1000 \
mpu 64

tc class add dev eth0 parent 1:0 classid 1:1 cbq bandwidth 10Mbit rate 10Mbit \
allot 1514 cell 8 weight 1Mbit prio 8 maxburst 20 avpkt 1000

tc class add dev eth0 parent 1:1 classid 1:2 cbq bandwidth 10Mbit rate 3Mbit \
allot 1514 cell 8 weight 100Kbit prio 3 maxburst 20 avpkt 1000 split 1:0

tc class add dev eth0 parent 1:1 classid 1:3 cbq bandwidth 10Mbit rate 8Mbit \
allot 1514 cell 8 weight 800Kbit prio 7 maxburst 20 avpkt 1000 split 1:0

tc filter add dev eth0 parent 1:0 protocol ip prio 100 route
------------< snip <------< snip <------< snip <------------

I get:

------------< snip <------< snip <------< snip <------------
root@rana:~# tc filter show
root@rana:~# tc class show
root@rana:~# tc qdisc show
qdisc cbq 1: dev eth0 rate 10Mbit (bounded,isolated) prio no-transmit
root@rana:~#
------------< snip <------< snip <------< snip <------------

As you can see the qdisc is added, but the class and filter entries don't
seem to work.

If I type the same filter rule multiple times, it allows it so I don't think
it is added at all. The class entries seem to be added because I get EEXIST
if I add the same rule multiple times, but it does not show up in ``tc class
show'' - any ideas?
