eBPF Strengthens SR-IOV to Be Powerful
summary
Implements eBPF-based clusterIP resolution for SR-IOV and macvlan interfaces so pods using virtual functions can reach services without dual CNIs, using eBPF maps synced from the API server. Claims: up to 25% lower latency and 15% higher throughput versus proxy/iptables approaches; measured per-packet latencies of about 27 µs (vs ~36 µs in an alternate path). Provides an SP component that integrates with existing CNI datapaths and shows real performance gains.
