Look at the first ODATA packet in the attached capture file. It has 2 options
(Length not included), Syn and Join, but Wireshark shows three Syn options
instead. Also, there are only 100 bytes of data in the packet, but Wireshark
shows 112 (the first 12 bytes actually belong to the options).

You can see similar errors on other packets, for example the first SPM packet
is shown to have 3 Fin options.
