I don't have an explicit use case right now, but it gives somewhat
greater flexibility in classifying packets.
Particularly in the ingress mode with ifb (this would mostly apply to
an end-device, not so much to traffic being forwarded through a
router). We cannot set DSCP flags on incoming packets, since they just
arrived. However, we can use a filter on cake to assign them
explicitly to a tin.
We can do the following:
#tc qdisc add dev enp1s0 ingress handle ffff
#tc qdisc add dev ifb0 root handle 8002 cake bandwidth 11800kbit
#tc filter add dev ifb0 parent 8002: protocol ip \
u32 match ip src 18.104.22.168/32 \
action skbedit priority 8002:3
#tc filter add dev enp1s0 parent ffff: protocol all \
u32 match u32 0 0 \
action mirred egress redirect dev ifb0
