## Notes
### BPF For/While Loop Support
This project requires for/while loop support with BPF. Older kernels will not support this and output an error such as:
```
libbpf: load bpf program failed: Invalid argument
libbpf: -- BEGIN DUMP LOG ---
libbpf:
back-edge from insn 113 to 100
libbpf: -- END LOG --
libbpf: failed to load program 'xdp_prog'
libbpf: failed to load object '/etc/xdpfw/xdpfw_kern.o'
```
