tools: ynl: convert tc and tc-filter-add samples to selftest

2026-03-10T00:02:26+00:00

Convert tc.c and tc-filter-add.c to produce KTAP output with kselftest_harness. Merge the two tests together. They both test TC one is testing qdisc and the other classifiers but they can easily live in a single selftest. Make the test spawn a new netns, and run the operations on lo to avoid onerous setup and cleanup.

tools: ynl: convert rt-link sample to selftest

2026-03-10T00:02:26+00:00

Convert rt-link.c to use kselftest_harness.h with FIXTURE/TEST_F. Move rt-link from BINS to TEST_GEN_PROGS.

tools: ynl: convert ovs sample to selftest

2026-03-10T00:02:26+00:00

Convert ovs.c to produce KTAP output with kselftest_harness. The single "crud" test creates a new OVS datapath, fetches it back by name, then dumps all datapaths verifying the new one appears. IIRC I added this test because ovs is a genetlink family but has a family-specific fixed header.

tools: ynl: add YNL test framework

2025-11-27T01:58:49+00:00

Add a test framework for YAML Netlink (YNL) tools, covering both CLI and ethtool functionality. The framework includes: 1) cli: family listing, netdev, ethtool, rt-* families, and nlctrl operations 2) ethtool: device info, statistics, ring/coalesce/pause parameters, and feature gettings The current YNL syntax is a bit obscure, and end users may not always know how to use it. This test framework provides usage examples and also serves as a regression test to catch potential breakages caused by future changes.
