OK its probably too late :)
Here is a script I would use/adapt somehow...
(You probably need 1024 subclasses, this script uses 256 slots only)
ETH=eth7
NUMGROUPS=256
RATE="rate 5Mbit"
ALLOT="allot 4000"
MASK=$(($NUMGROUPS-1))
HMASK=$(printf %02x $MASK)
LIST=`seq 0 $MASK`
TC="tc"
export PATH=/sbin:/usr/sbin:$PATH
# Not sure 10Gbit can be reached without TSO...
#ethtool -K $ETH tso off
$TC qdisc del dev $ETH root 2>/dev/null
$TC qdisc add dev $ETH root handle 1: est 0.5sec 4sec cbq avpkt 1200 rate
10Gbit \
bandwidth 10Gbit
$TC class add dev $ETH parent 1: classid 1:1 \
est 0.5sec 4sec cbq allot 8000 mpu 64 \
rate 10Gbit prio 1 avpkt 1200 bounded
$TC filter add dev $ETH parent 1: protocol ip prio 10 u32
$TC filter add dev $ETH parent 1: protocol ip prio 10 handle 8: u32 divisor
$NUMGROUPS
for i in $LIST
do
slot=$(printf %02x $(($i+16)))
hexa=$(printf %02x $i)
$TC class add dev $ETH parent 1:1 classid 1:$slot \

$TC qdisc add dev $ETH parent 1:$slot handle $slot: est 0.5sec 4sec sfq limit

$TC filter add dev $ETH parent 1: protocol ip prio 100 u32 ht 8:$hexa: \
