After run bonding.py in Rhel8.2 with Avocado(version: 82.0), it shows "FAIL: bond name already exists on local machine".

【Test Step】
Step 1. Prepare 2 terminals while each one is equipped with 1 Network-Card. Then connect the 2 Network-Cards with each other.
※Network-Card: Broadcom 5719 QP 1G (1G/100M/10M) Network Interface Card PCIe x4 LP
→The Network-Card has 4 ports. We connect 2 of them with each one, like below:

Step 2. Edit yaml file in SUT5: /root/tests/tests/avocado-misc-tests/io/net/bonding.py.data/bonding.yaml

Step 3. Run bonding.py in SUT5:

Hi @Gene-Lo , I see that the interface is already created before running this test.

2020-09-23 09:34:58,446 process          L0416 DEBUG| [stdout] 10: bondtest: <NO-CARRIER,BROADCAST,MULTICAST,MASTER,UP> mtu 1500 qdisc noqueue state DOWN mode DEFAULT group default qlen 1000

The bond test already does this in the test_setup routine. Please remove the bonding device and try running the test again.

Good luck!

Ｉ. After we run bonding.py again with Network-Card, Broadcom_5719, the result is still FAIL:

【Test Step】

1. Prepare 2 terminals while each one is equipped with 1 Network-Card. Then connect the 2 Network-Cards with each other.

2. Change Network-Cards's setting via below SOP:
   SOP of Avocado Network-Card Settings.pdf

3. Edit yaml file in SUT5: /root/tests/tests/avocado-misc-tests/io/net/bonding.py.data/bonding.yaml
   

4. Input "ip a" to check current status of interface:
   

5. Run bonding.py in SUT5

【Test log】

1. job.log: Gererated by Avocado
   job.log

2. SOL_log: Record the whole process about how we change Network-Cards' settings and run bonding.py

3. Manual_Test_log: We try to run bonding.py's commands by manual, but it shows "No such file or directory"

4. Configuration

==============================================

II. We tried to use the same method to run bonding.py but with different types of Network-Card, Marvell 2-PORT E'NET (2X10 10Gb), and the result is still FAIL:
