// The ip_option_information structure describes the options to be
// included in the header of an IP packet. The TTL, TOS, and Flags
// values are carried in specific fields in the header. The OptionsData
// bytes are carried in the options area following the standard IP header.
// With the exception of source route options, this data must be in the
// format to be transmitted on the wire as specified in RFC 791. A source
// route option should contain the full route - first hop thru final
// destination - in the route data. The first hop will be pulled out of the
// data and the option will be reformatted accordingly. Otherwise, the route
// option should be formatted as specified in RFC 791.
