I saw this too, and I guess what I can't figure out is why socket options to extract IP options on a raw IP socket (or perhaps any datagram socket) are not sufficient. There are no "IP options packets"; the options are already associated with a packet bound to a socket. Or for packets transiting the host. Is this specifically to support an RSVP implementation when the FreeBSD platform is acting as a router? I'm also wondering why perhaps BPF isn't a mechanism which can be used, but perhaps that's much too low a level an interface. louie To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-net" in the body of the message
