====================
selftest: packetdrill: Import TFO server tests.
The series imports 15 TFO server tests from google/packetdrill and
adds 2 more tests.
The repository has two versions of tests for most scenarios; one uses
the non-experimental option (34), and the other uses the experimental
option (255) with 0xF989.
Basically, we only import the non-experimental version of tests, and
for the experimental option, tcp_fastopen_server_experimental_option.pkt
is added.
The following tests are not (yet) imported:
* icmp-baseline.pkt
* simple1.pkt / simple2.pkt / simple3.pkt
The former is completely covered by icmp-before-accept.pkt.
The later's delta is the src/dst IP pair to generate a different
cookie, but supporting dualstack requires churn in ksft_runner.sh,
so defered to future series. Also, sockopt-fastopen-key.pkt covers
the same function.
The following tests have the experimental version only, so converted
to the non-experimental option:
* client-ack-dropped-then-recovery-ms-timestamps.pkt
* sockopt-fastopen-key.pkt
For the imported tests, these common changes are applied.
* Add SPDX header
* Adjust path to default.sh
* Adjust sysctl w/ set_sysctls.py
* Use TFO_COOKIE instead of a raw hex value
* Use SOCK_NONBLOCK for socket() not to block accept()
* Add assertions for TCP state if commented
* Remove unnecessary delay (e.g. +0.1 setsockopt(SO_REUSEADDR), etc)
With this series, except for simple{1,2,3}.pkt, we can remove TFO server
tests in google/packetdrill.

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.
