Subject: tc filter show not displaying anything

Hello, all.  I'm starting to feel really stupid and showing my newbidity
to tc.  I do a:
tc filter show dev eth1
and nothing is displayed but I suspect the filter is there because if I
try to add it again, the kernel complains with:
RTNETLINK answers: File exists
We have an error talking to the kernel

Here is what I have put together so far (disregard the silly ports - it
is just for netcat testing):

tc qdisc add dev eth1 root handle 1: hfsc default 20
tc class add dev eth1 parent 1: classid 1:1 hfsc sc rate 1490kbit ul rate 1490kbit
tc class add dev eth1 parent 1:1 classid 1:20 hfsc rt rate 800kbit ls rate 200kbit
tc qdisc add dev eth1 parent 1:20 handle 1201 sfq perturb 10
tc class add dev eth1 parent 1:1 classid 1:10 hfsc rt umax 16000kbit dmax 13ms rate 400kbit ls rate 1000kbit
tc qdisc add dev eth1 parent 1:10 handle 1101 sfq perturb 10
iptables -t mangle -A POSTROUTING  -p 6 --syn --dport 443 -j CONNMARK --set-mark 0x10
iptables -t mangle -A POSTROUTING  -p 6 -j CONNMARK --restore-mark

I then did:

root@...tswitch01:~# tc filter add dev eth1 parent 1:1 protocol ip prio 1 handle 0x10 fw flowid 1:10
root@...tswitch01:~# tc filter show dev eth1
root@...tswitch01:~# tc filter show parent 1:1

What simple, practical thing did I mangle? Thanks - John
