From: Ralf Lici <[email protected]> To verify that netlink notifications are correctly emitted and contain the expected fields, this commit uses the tools/net/ynl/pyynl/cli.py script to create multicast listeners. These listeners record the captured notifications to a JSON file, which is later compared to the expected output.
Since this change introduces additional dependencies (jq, pyyaml, jsonschema), the tests are configured to check for their presence and conditionally skip the notification check if they are missing.
