Subject: teql and vlan not compatible?

Hello,

are teql and vlan mutually exclusive?

I've done some tests the last days that drove me crazy, until I found an an 
old (2003) message on the linux.drivers.vlan list :

"vlan + teql qdisc problem"

http://osdir.com/ml/linux.drivers.vlan/2003-02/msg00050.html

<quote>
tc qdisc add dev vlan0003 root teql0
then i can no longer ping 10.0.0.2 from 10.0.0.1.
The moment I add qdisc it stop working.
When I remove qdisc - I can ping again.
</quote>

While my setup is more complicated, the problem is the same.
I cannot even see any arp requests on the wireshark after I have a teql'd 
interface on a vlan like this
"tc qdisc replace dev eth9.42 root teql0"

Is this a fundamental impossibility or is there simply some secret magic I 
just haven't found documented?
Above thread is the only google hit for "teql & vlan"

Thanks for any hint!
