Daniel, I'd have som preliminary patches for trafgen ready to introduce the csumudp6 and csumtcp6 trafgen helper functions (UDP/TCP checksum using IPv6 pseudo headers). If you want I can push them after some further testing later today. Eric, would these to helpers be sufficient for your use case or do you need any additional trafgen functionality? -- To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
