How do you want to enable wire/fibre flow control, e.g., from Europe to USA? You are not guaranteed any hardware based flow control. And as of software flow control, you need precise timing of UDP packets to keep desired packet rate. How to do it at speeds about 5.5Gbps, that is my question. -- Lukáš Hejtmánek - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
