Acked from a doc point of view. Maintainers should check if the instructions are okay.

This note should be below the compilation command.
When adding more BPF examples, it will be easily outdated.
We could say "to build other examples, more arguments may be required".
About the compiler options, I suggest to name them: -I, -L?

I agree, I will make the change.

Thanks, can we get some update on BPF examples. Reasoning, we are planning to add dpdk-example specific BPF code but not in test/bpf.
