DPDK relies on pkg-config(1) to provide correct parameters for

This commit introduces the flexible interface. This
interface allows the core code to operate in PF mode (direct
hardware access) or bifurcated mode (hardware configured via
kernel driver). This driver currently only supports PF mode
but bifurcated mode will be added in a future DPDK patch-set.

The header file dlb2_priv.h is used internally by the PMD.
It include constants, macros for device resources,
structure definitions for hardware interfaces and
software state, and various forward-declarations.
The header file rte_pmd_dlb2.h will be exported in a
subsequent patch, but is included he
Add headers containing structs and constants shared between
the PMD and the shared code. The term shared code refers to
the code that implements the hardware interface. The shared code
is introduced in the probe patch, and then is extended as
additional eventdev PMD entry points are added to the p
Add miscellaneous inline functions that may be called
from multiple files. These functions include inline
assembly of new x86 instructions, such as movdir64b,
since they are not available as builtin functions in
the minimum supported GCC version.

Adds the meson build infrastructure, which includes
compile-time constants in rte_config.h. DLB2 is
only supported on Linux 64 bit X86 platforms at this time.
Adds announcement of availability for the new driver
for Intel Dynamic Load Balancer 2.0 hardware.

PMD adds support for the Intel Dynamic Load Balancer 2.0 (DLB2)
hardware.
The DLB2 is a PCIe device that provides load-balanced, prioritized
scheduling of core-to-core communication. The device consists of
queues and arbiters

These entry points are NO-OPS. DLB does not support
reconfiguring individual queues or ports. The entire device
must be reconfigured.

The PMD uses a public interface to allow applications to
control the token pop mode. Supported token pop modes are
as follows, and they impact core scheduling affinity for
ldb ports.
AUTO_POP: Pop the CQ tokens immediately after dequeueing.
