Currently, many programs under sample/bpf often include individual macros by directly including the header under "linux/" rather than using the "vmlinux.h" header. However, there are some problems with migrating to "vmlinux.h" because there is no definition for utility functions such as endianness conversion (ntohs/htons). Fortunately, the xdp_sample program already has a function that can be replaced to solve this problem. Therefore, this commit attempts to separate these functions into a file called net_shared.h to make them universally available. Additionally, this file includes network-related macros that are not defined in "vmlinux.h". (inspired by 'selftests' bpf_tracing_net.h) Signed-off-by: Daniel T.

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.
