The example suite 'example_skip_suite' provides a 'suite_init' callback named example_skip_suite_init() which marks the entire suite as skipped using kunit_mark_skipped(). This demonstrates a way for conditionally skipping test suites when any prerequisites for kunit_suite execution are not met. The 'suite_init' callback can perform any necessary checks and mark the suite as skipped, preventing all test cases from executing while also indicating why the suite was skipped.
