# `src/l2.rs`'s raw AF_PACKET/SOCK_RAW transport: this crate is
# `#![forbid(unsafe_code)]` crate-wide (`src/lib.rs`), which rules out a
# direct `libc` `socket()`/`bind()`/`sendto()`/`recvfrom()` implementation
# (that would require `unsafe extern "C"` calls in this crate's own
# source, and `forbid` cannot be locally overridden). `nix` wraps those
# same syscalls in a fully safe Rust API (`unsafe` lives inside `nix`'s
# own crate, not this one) and is gated to `target_os = "linux"` here so
# no other build target's dependency graph grows because of it — see
# `src/l2.rs`'s own module doc comment, "Why `nix`, not raw `libc`
# `unsafe` syscalls — a flagged judgment call", for the full reasoning.
