I was trying to set up an ingress link sharing env. by tc & htb qdisc. and I made two macvlan subinterfaces(say mgmt, data) under a parent physical interface enp8s0f0 and enp8s0f0's speed is 1000 mbit/s.
enp8s0f0 | -- mgmt(f6:cb:f6:4d:28:df)
| -- data(32:b2:ee:5c:1b:0d)
I made the following configuration based on ifb and tc setting. My intention is to guarantee 100mbit/s inbound bandwidth for mgmt. The setup will redirect all inbound traffic to enp8s0f0-ing and do the egress rules based on dst mac address.
sudo ip link add enp8s0f0-ing type ifb
sudo ip link set dev enp8s0f0-ing up qlen 1000
sudo tc qdisc add dev enp8s0f0 handle ffff: ingress
sudo tc filter add dev enp8s0f0 parent ffff: protocol all u32 match u32 0 0 action mirred egress redirect dev enp8s0f0-ing
sudo tc qdisc add dev enp8s0f0-ing root handle 1: htb default 20
sudo tc class add dev enp8s0f0-ing parent 1: classid 1:1 htb rate 1000mbit ceil 1000mbit
sudo tc class add dev enp8s0f0-ing parent 1:1 classid 1:10 htb rate 100mbit ceil 1000mbit
sudo tc class add dev enp8s0f0-ing parent 1:1 classid 1:20 htb rate 900mbit ceil 1000mbit
sudo tc filter add dev enp8s0f0-ing parent 1:0 prio 1 u32 match ether dst f6:cb:f6:4d:28:df classid 1:10
But it is not working, although i saw the traffic go to respective flows. That is when dest mac is f6:cb:f6:4d:28:df, it goes to 1:10; when other dest mac, it goes to 1:20. Seems only link sharing on ifb is not working? (I also tried the setup on physical interface enp8s0f0 for egress traffics, it works fine except for the accuracy for the ratio of link sharing)
