When adding new test case files, you should add any necessary configs needed to run them in tools/testing/selftests/tc-testing/config, if they aren't already there.

For example, your ATM patch should also add the following config options to that file:

CONFIG_ATM=y
CONFIG_NET_SCH_ATM=m


Hi Victor:
	Thank you for your testing. I will add config in V3. It might be
better to generate executable test suites based on kernel config.
However, this feature does not seem to be supported currently. Or This feature can be added later.
