Run rxtimestamp as part of TEST_PROGS. Analogous to other tests, add new rxtimestamp.sh wrapper script, so that the test runs isolated from background traffic in a private network namespace. Also ignore failures of test case #6 by default. This case verifies that a receive timestamp is not reported if timestamp reporting is enabled for a socket, but generation is disabled. Receive timestamp generation has to be enabled globally, as no associated socket is known yet. A background process that enables rx timestamp generation therefore causes a false positive. Ntpd is one example that does. Add a "--strict" option to cause failure in the event that any test case fails, including test #6. This is useful for environments that are known to not have such background processes.

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 Restructured Text 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.
