tools: ynl: move ethtool.py to selftest

2026-04-12T18:23:49+00:00

We have converted all the samples to selftests. This script is
the last piece of random "PoC" code we still have lying around.
Let's move it to tests.

tools: ynl: tests: fix leading space on Makefile target

2026-04-10T03:41:40+00:00

The ../generated/protos.a rule had a spurious leading space before the
target name. In make, target rules must start at column 0; only recipe
lines are indented with a tab. The extra space caused make to misparse
the rule.

Remove the leading space to match the style of the adjacent
../lib/ynl.a rule.

tools: ynl: convert rt-route sample to selftest

2026-03-10T00:02:27+00:00

Convert rt-route.c to use kselftest_harness.h with FIXTURE/TEST_F.
This is the last test to convert so clean up the Makefile.

Validate that the connected routes for 192.168.1.0/24 and
2001:db8::/64 appear in the dump.

Output:

it's invoked via the devlink.sh wrapper which sets up netdevsim.

tools: ynl: add netdevsim wrapper library for YNL tests

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

Some tests need netdevsim setup which is painful to do from C.

Add ynl_nsim_lib.sh, a shared library providing nsim_setup and
nsim_cleanup functions for tests that need a netdevsim device.

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 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.

  1..1
  # Starting 1 tests from 1 test cases.
  #  RUN           ovs.crud ...
  # get:
  # ynl-test(3): pid:0 cache:256
