…etworking Implements a robust Prow CI test to detect TCP RST storms during OpenShift networking component restarts, targeting the critical OCPBUGS-77510 bug in OVN-Kubernetes serviceUpdateNotNeeded() nil pointer comparison. Key Features: - Progressive testing: 6 test combinations (3 scales × 2 trigger methods) - Multi-scale validation: 10, 50, and 200 pod infrastructures - Dual trigger support: OVN-Kubernetes and API server restart methods - Resilient execution: Continues through all tests despite individual failures - Comprehensive monitoring: TCP RST packet capture via tcpdump - Rich artifacts: Detailed logs and test evidence preservation Test Coverage: - Small scale (10 pods) with OVN and API restart triggers - Medium scale (50 pods) with OVN and API restart triggers - Large scale (200 pods) with OVN and API restart triggers - Graceful fallback to baseline monitoring on permission issues - 35-minute timeout ensuring complete test execution

Update OCPBUGS-77510 test jobs to use the correct custom release image for 4.21 (ci-ln-niy7v42) instead of the 4.20 image (ci-ln-4zh40jk). This ensures 4.21 tests run against the appropriate release build. Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
