test_kmod.sh reported false failure when module not present. Check test_bpf.ko is present in the path before loading it. Two cases to be addressed here, In the development process of test_bpf.c unit testing will be done by developers by using "insmod $SRC_TREE/lib/test_bpf.ko" On the other hand testers run full tests by installing modules on device under test (DUT) and followed by modprobe to insert the modules accordingly.
