Subject: [net-next-2.6 PATCH v6 6/7 RFC] TCPCT part 1f: Initiator Cookie =>
 Responder

Calculate and format TCP_COOKIE SYN option.

Create (and destroy) cookie data structures.

This is a significantly revised implementation of an earlier (year-old)
patch that no longer applies cleanly, with permission of the original
author (Adam Langley):

    http://thread.gmane.org/gmane.linux.network/102586

Requires:
   TCPCT part 1c: sysctl_tcp_cookie_size, socket option TCP_COOKIE_TRANSACTIONS
   TCPCT part 1d: define TCP cookie option, extend existing struct's
