# Test various interface configuration scenarios. Observe that configurations

# deemed valid by mlxsw succeed, invalid configurations fail and that no traces

# are produced. To prevent the test from passing in case traces are produced,

# the user can set the 'kernel.panic_on_warn' and 'kernel.panic_on_oops'
