This is in:
def get_max_lanes(port):
"""
Get the $port's maximum number of lanes.
Return: number of lanes, e.g. 1, 2, 4 and 8.
"""
cmd = "devlink -j port show %s" % port
stdout, stderr = run_command(cmd)
assert stderr == ""
values = list(json.loads(stdout)['port'].values())[0]
We're expecting stderr to be empty, but since this command triggers a
warning / error, the `assert stderr == ""` fails.
This issue does not exist with 6.5.0-4-generic (on node riccioli, it's
failing with L-ibm)
