Some distributions enable rp_filter globally by default, which can interfere with various test cases. To address this, many tests explicitly disable rp_filter within their scripts.
To avoid duplication and ensure consistent behavior across tests, this patch moves the rp_filter configuration into setup_ns, applied immediately after a new namespace is created. This change ensures that all namespace-based tests inherit the appropriate rp_filter settings, simplifying individual test scripts and improving maintainability.
BTW, the patch 4/6 for srv6 is a bit large. Please tell me if you think I need to break this one.
