Then, for each port on the target make the Traffic Generator +transmit a packet to the port of arbitrary size less than the MTU of +the target port, checking that the same amount of frames and bytes +are received back by the Traffic Generator from the port. + +Ensure that the ``speed_capabilities.cfg`` file correctly reflects the speeds +the device is expected to run at. + + +Test Case : Speed Capabilities Test +=================================== + +1. Use testpmd to retrieve the speed information that the interface is linked at:: + + testpmd> show port info <PORT_ID> + +2. Compares the speed value against the rate in the speed_capabilities.cfg file. + The supported options for expected speeds are 1G, 10G, 25G, 40G, and 100G. Each interface must have an expected speed associated with it. + Example file below:: + + [suite] + expected_speeds={'interface1': '10G', 'interface2': '100M'} + + +3. Verifies that the speeds matches accordingly. + +4.
