Testing
-------
Next to the BPF toolchain, the kernel also ships a test module that contains
various test cases for classic and internal BPF that can be executed against
the BPF interpreter and JIT compiler. It can be found in lib/test_bpf.c and
enabled via Kconfig:
CONFIG_TEST_BPF=m
After the module has been built and installed, the test suite can be executed
via insmod or modprobe against 'test_bpf' module. Results of the test cases
including timings in nsec can be found in the kernel log (dmesg).
