From b86761ff6374813cdf64ffd6b95ddd1813c435d8 Mon Sep 17 00:00:00 2001 From: Jakub Kicinski Date: Thu, 4 Apr 2024 19:45:22 -0700 Subject: selftests: net: add scaffolding for Netlink tests in Python Add glue code for accessing the YNL library which lives under tools/net and YAML spec files from under Documentation/. Automatically figure out if tests are run in tree or not. Since we'll want to use this library both from net and drivers/net test targets make the library a target as well, and automatically include it when net or drivers/net are included. Making net/lib a target ensures that we end up with only one copy of it, and saves us some path guessing. Add a tiny bit of formatting support to be able to output KTAP from the start.
