Ha, good thing you mentioned it I was just about to go back to patch writing. Interesting approach. IPV6_DONTFRAG is (again) not documented in ipv6(7) so I had no idea this exists :) FYI: From looking at the linux code it looks like it's possible to set IPV6_DONTFRAG per-sendmsg() call (in the cmsg field, see ip6_datagram_send_ctl() in linux) so this could also be a per-interface option. Awesome work Juliusz! --Daniel _______________________________________________ Babel-users mailing list [email protected] https://alioth-lists.debian.net/cgi-bin/mailman/listinfo/babel-users
