Description

In test script sub_port_interfaces/test_show_subinterface.py, we want to create the subinterface and it should inherit the ancestor's speed. But from the rest result , we can see that, the ancestor's speed is 1G, which should be inherited by the subinterface. But actually, the speed of the new created subinterface is 40G. We suspect it is an image issue on kvm testbed.

Steps to reproduce the issue:

1. Run the script sub_port_interfaces/test_show_subinterface.py on kvm testbed.

Describe the results you received:

>           pytest_assert(status.get("speed") == config["speed"],
                          "subinterface %s should have inherited speed as %s, actual speed %s"
                          % (subintf, config["speed"], status.get("speed")))
E           Failed: subinterface Ethernet4.20 should have inherited speed as 1G, actual speed 40G
