Convert ethtool.c to use kselftest_harness.h with FIXTURE/TEST_F.
Move ethtool from BINS to TEST_GEN_FILES and add ethtool.sh wrapper
which sets up a netdevsim device before running the test binary.

Output:

  TAP version 13
  1..2
  # Starting 2 tests from 1 test cases.
  #  RUN           ethtool.channels ...
  #    nsim0: combined 1
  #            OK  ethtool.channels
  ok 1 ethtool.channels
  #  RUN           ethtool.rings ...
  #    nsim0: rx 512 tx 512
  #            OK  ethtool.rings
  ok 2 ethtool.rings
  # PASSED: 2 / 2 tests passed.
  # Totals: pass:2 fail:0 xfail:0 xpass:0 skip:0 error:0

tools: ynl: move samples to tests 2026-03-10T00:02:25+00:00 Jakub Kicinski kuba@kernel.org 2026-03-07T03:36:21+00:00 e0aa0c61758f517ded2befa084ebcad93809b421 The "samples" were always poor man's tests (used to manually confirm that C YNL works). Move all C sample programs from tools/net/ynl/samples/ to tools/net/ynl/tests/, "merge" the Makefiles. The subsequent changes will convert each sample into a proper KTAP selftests. Since these are now tests rather than samples - default to enabling asan. After all we're testing user space code here. Sort the gitignore while at it, the page-pool entry was a leftover so delete it.
