Hi, all
When I configure the qos rules to one linux bond port which has been attached
to openvswitch port,
I find the tc rules are not what I configured.
Fllow the steps bellow to reproduce it:
1) Use linux bond
[root@host1 home]# cat /proc/net/bonding/bond0
Ethernet Channel Bonding Driver: v3.7.1 (April 27, 2011)
Bonding Mode: IEEE 802.3ad Dynamic link aggregation
Transmit Hash Policy: layer3+4 (1)
MII Status: up
MII Polling Interval (ms): 100
Up Delay (ms): 0
Down Delay (ms): 0
802.3ad info
LACP rate: slow
Min links: 0
Aggregator selection policy (ad_select): stable
Active Aggregator Info:
Aggregator ID: 9
Number of ports: 1
Actor Key: 9
Partner Key: 32969
Partner Mac Address: 00:23:04:ee:be:0b
Slave Interface: enp2s0f0
MII Status: up
Speed: 1000 Mbps
Duplex: full
Link Failure Count: 1
Permanent HW addr: 50:57:a8:e1:d9:aa
Slave queue ID: 0
Aggregator ID: 9
Actor Churn State: none
Partner Churn State: none
Actor Churned Count: 0
Partner Churned Count: 0
details actor lacp pdu:
system priority: 65535
port key: 9
port priority: 255
port number: 1
port state: 61
details partner lacp pdu:
system priority: 32667
oper key: 32969
port priority: 32768
port number: 16641
port state: 61
Slave Interface: enp2s0f1
MII Status: down
Speed: 1000 Mbps

Aggregator ID: 8
Actor Churn State: churned
Partner Churn State: churned
Actor Churned Count: 1
Partner Churned Count: 1
details actor lacp pdu:
system priority: 65535
port key: 0
port priority: 255
port number: 2
port state: 69
details partner lacp pdu:
system priority: 65535
oper key: 1
port priority: 255
port number: 1
port state: 1
2) Create ovs bridge and add the port to it
ovs-vsctl add-br testbr
ovs-vsctl add-port testbr bond0
3) Configure the qos for bond0
ovs-vsctl set port bond0 qos=@qos -- --id=@qos create qos type=linux-htb
queues:0=@queue_data -- --id=@queue_data create queue
other-config:min-rate=1200000000 other-config:max-rate=2000000000
4)Show the tc rules using tc command
tc class show dev bond0
class htb 1:1 parent 1:fffe prio 0 rate 1000Mbit ceil 1000Mbit burst 1625b
cburst 1625b
class htb 1:fffe root rate 1000Mbit ceil 1000Mbit burst 1500b cburst 1500b
You could find the ceil and the rate is not what I specified.
Could you help me to confirm the problem and fix it?
