-/*
- * Minimal BPF assembler
- *
- * Instead of libpcap high-level filter expressions, it can be quite
- * useful to define filters in low-level BPF assembler (that is kept
- * close to Steven McCanne and Van Jacobson's original BPF paper).
- * In particular for BPF JIT implementors, JIT security auditors, or
- * just for defining BPF expressions that contain extensions which are
- * not supported by compilers.
- *
- * How to get into it:
- *
- * 1) read Documentation/networking/filter.txt
- * 2) Run `bpf_asm [-c] <filter-prog file>` to translate into binary
- *    blob that is loadable with xt_bpf, cls_bpf et al. Note: -c will
- *    pretty print a C-like construct.
