/*
 * 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.
