[iotg][tgl-up3] iPerf tests fail because of invalid command options

[Doug Jacobs]

[Summary] Run the iperf3 tests and the tests themselves pass, but the final command to get information about the ethernet interface seems to fail because the command or the options are invalid.

Image: iotg-focal-desktop-20210813.img

[Steps to reproduce]
Connect TLG-UP3 to Ethernet network with a iperf3 server running
Select iperf tests from the desktop 20.04 automated test suite

[Expected result]
All tests should pass

[Actual result]
iperf tests fail due to an invalid command line command

[Failure rate] 100%

Did you connect enp0s30f4 with a network and make sure there is IP assigned by DHCP ?

The TGL-UP3 only has 1 physical Ethernet port, but Ubuntu sees 2 separate interfaces. There is no way to connect an Ethernet cable to enp0s31f6.

So the output from the test is incorrect. It should just fail because the interface is not configured (no IP address, etc.)
