$NetBSD: README,v 1.2 2025/04/17 13:08:55 gdt Exp $ This directory contains kernel source for NPF, the NetBSD Packet Filter, but the README also applies to: src/lib/npf: library for interacting with in-kernel npf implementation src/usr.bin/npf: tools for configuring in-kernel npf and for testing assorted supporting files (rc.d, modules, tests) Previously, NetBSD considered https://github.com/rmind/npf/ to be the upstream location. There is no obligation to file PRs when changing npf in NetBSD. Please avoid unecessary divergence in order to ease future syncing from this repo, but this caution should not block improvements.
