Hello again,

Results in my last email were accidentally using fq_codel for the 
ingress qdisc. Now I set it up with cake, commit 402f05c. The commands I 
used are listed below.

Regards,

Kristjan

export TC=~/local/src/iproute2-cake-next/tc/tc

$TC qdisc add dev enp4s0 root cake bandwidth 850Kbit docsis nat dual-srchost ack-filter

ip link add name ifb0 type ifb

$TC qdisc del dev enp4s0 ingress

$TC qdisc add dev enp4s0 handle ffff: ingress

$TC qdisc del dev ifb0 root

$TC qdisc add dev ifb0 root cake bandwidth 4250Kbit docsis nat dual-dsthost ingress

ip link set ifb0 up

$TC filter add dev enp4s0 parent ffff: protocol all prio 10 u32 match u32 0 0 flowid 1:1 action mirred egress redirect dev ifb0
