Hi, I have been playing around with IPv6 flow labels on UDP under Linux. When using flow labels on a socket, I seem unable to set the per-hop options header on a per-packet basis. It works if I set the per-hop options header while acquiring the flow label from the kernel. I am wondering if Linux enforces the following from Appendix A of RFC2460: " All packets belonging to the same flow must be sent with the same source address, destination address, and flow label. If any of those packets includes a Hop-by-Hop Options header, then they all must be originated with the same Hop-by-Hop Options header contents (excluding the Next Header field of the Hop-by-Hop Options header). " Does anyone know if that is the case? Oh, and BTW is the API to obtain flow labels from the kernel documented somewhere else than in the source code?
