Convert devlink.c to use kselftest_harness.h with FIXTURE/TEST_F.
Move devlink from BINS to TEST_GEN_FILES in the Makefile since
it's invoked via the devlink.sh wrapper which sets up netdevsim.

Output:

  TAP version 13
  1..2
  # Starting 2 tests from 1 test cases.
  #  RUN           devlink.dump ...
  # netdevsim/netdevsim1337
  #            OK  devlink.dump
  ok 1 devlink.dump
  #  RUN           devlink.info ...
  # netdevsim/netdevsim1337:
  #   driver: netdevsim
  #   running fw:
  #     fw.mgmt: 10.20.30
  #            OK  devlink.info
  ok 2 devlink.info
  # PASSED: 2 / 2 tests passed.

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.
