Daniel Borkmann says: ==================== BPF updates These were still in my queue. Please see individual patches for details. I have rebased these on top of current net-next with Andrew's gcc union fixup [1] applied to avoid dealing with an unnecessary merge conflict.

+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

+including timings in nsec can be found in the kernel log (dmesg).
