This patch introduces a new bpf_skops_tx_timestamping() function that prepares the "struct bpf_sock_ops" ctx and then executes the sockops BPF program. The subsequent patch will utilize bpf_skops_tx_timestamping() at the existing TX timestamping kernel callbacks (__sk_tstamp_tx specifically) to call the sockops BPF program. Later, four callback points to report information to user space based on this patch will be introduced.

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.
