I'm playing with L2TPNS (http://sourceforge.net/projects/l2tpns) - its an LNS done in software. Its approach is to receive packets via a tun device, encapsulate them in userland and then push them onto a LAC using sendto. I need to copy the TOS from the packets it receives into the header of the encapsulated packet, but I can't see any way of doing that (short of calling setsockopt for every packet). So my thought was to change the kernel so that you can pass in IP_TOS to sendmsg to specify a per-packet TOS. Does this sound like the right way to approach it? -- Alex Kiernan - : send the line "unsubscribe linux-net" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
