LARTC - Nov 2005 - tc qdisc replace failing

Hi,

Having issues getting a replace command working correctly. The error reported 
is "RTNETLINK answers: Invalid argument" which isn''t
descriptive or helpful.

The command i''m running is:

tc qdisc replace dev ppp0 parent 8001:D handle D: tbf rate 5Kbit burst 5kb 
latency 70ms

The idea being to replace an sfq with handle D and hopefully limit a certain 
user in my WRR class. If I delete the qdisc first and add with the below line 
it works.

tc qdisc del dev ppp0 parent 8001:D handle D:
tc qdisc add dev ppp0 parent 8001:D handle D: tbf rate 5Kbit burst 1540 
latency 70ms 

Anyone see what I''m doing wrong ?

I believe that replace is still broken so, if I''m correct, the answer
is, "replace does not work."
