[Julien: slightly change the drivers Config.in help text:
- rename net/ixgbe to net/intel/ixgbe
- change find -maxdepth value to 3

The Config.in comment in the dpdk package was wrong for a number of
reasons:
- It didn't mention the glibc dependency
- It didn't mention the gcc >= 4.9 dependency
- It mentioned a wchar dependency that isn't listed in the dpdk
dependencies
- It mentioned a dynamic library dependency that isn't listed in the
dpdk dependencies
- It used "kernel headers >= 4.19", while for brievity we use "headers
>= 4.19" everywhere in Buildroot
- Minor nit: DPDK was written allcaps, while we write package names
lower-case in Buildroot

This commit adds the integration of the Data Plane Development Kit (DPDK).
This commit does not enforce the use of UIO or VFIO kernel frameworks,
as DPDK's architecture supports userland memory mappings that do not require
these technologies. By maintaining this flexibility, DPDK can operate with
a broader range of hardware and software configurations.
Only the little endian targets are properly supported by DPDK. Big endian
was supported, mostly on Power8, but it has not been used for a while and
IBM is not strongly pushing any tests. Should big endian be supported
again, DPDK community will be welcoming any contributions.
Notes about license:
DPDK was released with the BSD-3-Clause license.
One network driver, the Google Virtual Ethernet (GVE) include files
under the MIT license. See [1] and [2].
There used to be GPL-2.0-only licensed kernel modules, but they got
removed in previous versions [K] [KNI], so Buildroot won't be used to compile
the GPL-2.0-only code.
There are also 2 files in "lib/eal/windows" under other licenses
(namely BSD-2-Clause, ISC and MIT) but they are parts of the Environment
Abstraction Library (EAL) for Microsoft Windows OS, it means they are
not used when compiling for the Linux targets of Buildroot.
The list of DPDK license exceptions is maintained at [2].
Add configuration options to enable DPDK examples and tests.
