Remove the redundant ethtool.h header file from tools/include/uapi/linux.
The file is unnecessary as the system uses the kernel's
include/uapi/linux/ethtool.h directly.

This commit duplicates the ethtool.h file from the include/uapi/linux
directory in the kernel source to the tools/include/uapi/linux directory.
This action ensures that the ethtool.h file used in the tools directory
is in sync with the kernel's version, maintaining consistency across the
codebase.
There are some checkpatch warnings in this file that could be cleaned up,
but I preferred to move it over as-is for now to avoid disrupting the code.

Instead of copying the whole header in, just add the struct definitions
we need for now. In the future it can be synced as a copy of in-tree
header if required.

This commit adds AF_XDP support to libbpf. The main reason for this is
to facilitate writing applications that use AF_XDP by offering
higher-level APIs that hide many of the details of the AF_XDP
uapi. This is in the same vein as libbpf facilitates XDP adoption by
offering easy-to-use higher level interfaces of XDP
functionality. Hopefully this will facilitate adoption of AF_XDP, make
applications using it simpler and smaller, and finally also make it
possible for applications to benefit from optimizations in the AF_XDP
user space access code. Previously, people just copied and pasted the
code from the sample application into their application, which is not
desirable.
The interface is composed of two parts:
* Low-level access interface to the four rings and the packet
* High-level control plane interface for creating and setting
up umems and af_xdp sockets as well as a simple XDP program.
