Original Text
-------------
   1. The client sends a SYN packet with a Fast Open option with a
      Length field of 0 (empty cookie field).

Corrected Text
--------------
   1. The client sends a SYN packet with a Fast Open option with a
      Length field of 2 (empty cookie field).

Notes
-----
A Nil fast-open option has an option length of 2.  A length field of zero would mean an invalid TCP option.
