Kuniyuki Iwashima 05b9f505fb selftest: packetdrill: Import sockopt-fastopen-key.pkt
sockopt-fastopen-key.pkt does not have the non-experimental
version, so the Experimental version is converted, FOEXP -> FO.

The test sets net.ipv4.tcp_fastopen_key=0-0-0-0 and instead
sets another key via setsockopt(TCP_FASTOPEN_KEY).

The first listener generates a valid cookie in response to TFO
option without cookie, and the second listner creates a TFO socket
using the valid cookie.

TCP_FASTOPEN_KEY is adjusted to use the common key in default.sh
so that we can use TFO_COOKIE and support dualstack.  Similarly,
TFO_COOKIE_ZERO for the 0-0-0-0 key is defined.

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
