 <<diffserv-gred_10-06>> 

I have attached the current script that I am using.  

$TC qdisc add dev $EDEV parent 2:20 gred setup DPs 3 default 2 grio
$TC qdisc change dev $EDEV parent 2:20 gred DP 1 limit $lim min $minTh
max $maxTh avpkt $avgPL burst $bursty bandwidth $netBand probability
0.02 prio 2
$TC qdisc change dev $EDEV parent 2:20 gred DP 2 limit $lim min $minTh
max $maxTh avpkt $avgPL burst $bursty bandwidth $netBand probability
0.04 prio 3
$TC qdisc change dev $EDEV parent 2:20 gred DP 3 limit $lim min $minTh
max $maxTh avpkt $avgPL burst $bursty bandwidth $netBand probability
0.06 prio 4
### GRED for AF2

$TC qdisc add dev $EDEV parent 2:30 gred setup DPs 3 default 2 grio
$TC qdisc change dev $EDEV parent 2:30 gred DP 1 limit $lim min $minTh
max $maxTh avpkt $avgPL burst $bursty bandwidth $netBand probability
0.02 prio 2
$TC qdisc change dev $EDEV parent 2:30 gred DP 2 limit $lim min $minTh
max $maxTh avpkt $avgPL burst $bursty bandwidth $netBand probability

$TC qdisc change dev $EDEV parent 2:30 gred DP 3 limit $lim min $minTh
max $maxTh avpkt $avgPL burst $bursty bandwidth $netBand probability
0.06 prio 4
### GRED for AF3

$TC qdisc add dev $EDEV parent 2:40 gred setup DPs 3 default 2 grio
$TC qdisc change dev $EDEV parent 2:40 gred DP 1 limit $lim min $minTh
max $maxTh avpkt $avgPL burst $bursty bandwidth $netBand probability
0.02 prio 2
$TC qdisc change dev $EDEV parent 2:40 gred DP 2 limit $lim min $minTh
max $maxTh avpkt $avgPL burst $bursty bandwidth $netBand probability
0.04 prio 3
$TC qdisc change dev $EDEV parent 2:40 gred DP 3 limit $lim min $minTh
max $maxTh avpkt $avgPL burst $bursty bandwidth $netBand probability
0.06 prio 4
### GRED for AF4

$TC qdisc add dev $EDEV parent 2:50 gred setup DPs 3 default 2 grio
$TC qdisc change dev $EDEV parent 2:50 gred DP 1 limit $lim min $minTh
max $maxTh avpkt $avgPL burst $bursty bandwidth $netBand probability
0.02 prio 2
$TC qdisc change dev $EDEV parent 2:50 gred DP 2 limit $lim min $minTh
max $maxTh avpkt $avgPL burst $bursty bandwidth $netBand probability
0.04 prio 3
$TC qdisc change dev $EDEV parent 2:50 gred DP 3 limit $lim min $minTh
max $maxTh avpkt $avgPL burst $bursty bandwidth $netBand probability
0.06 prio 4

Each DP3 line gives me an error.  If I comment it out the error goes
away.  The line translates to below.  

I get an error with the following line
++ /usr/sbin/tc qdisc change dev eth0 parent 2:20 gred DP 3 limit 60kb
min 10kb max 20kb avpkt 1500 burst 9 bandwidth 500kbit probability 0.06
prio 4 RTNETLINK answers: Invalid argument

after each DP 3 on each gred.

This starting happening after I upgraded to 2.6.18 from 2.4.20 kernel.
Anyone have any ideas?
