No functional changes here. Only add test to see if the orig_skb matches the usage of application SO_TIMESTAMPING. In this series, bpf timestamping and previous socket timestamping are implemented in the same function __skb_tstamp_tx(). To test the socket enables socket timestamping feature, this function skb_tstamp_tx_report_so_timestamping() is added. In the next patch, another check for bpf timestamping feature will be introduced just like the above report function, namely, skb_tstamp_tx_report_bpf_timestamping(). Then users will be able to know the socket enables either or both of features.

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.
