As the hardware determines which core will process which packet,
performance is boosted by direct cache warming/stashing as well
as by providing biasing for core-to-flow affinity, which ensures
that flow-specific data structures can remain in the core’s cache.
This patch enables the one cache line data stashing for packet
annotation data and packet context

The portal driver is bound to DPIO objects discovered on the fsl-mc bus and
provides services that:
- allow other drivers, such as the Ethernet driver, to enqueue and dequeue
frames for their respective objects
A system will typically allocate 1 DPIO object per CPU to allow queuing
operations to happen simultaneously across all CPUs.

Add support for using VFIO for dpaa2 based fsl-mc bus.
There are some differences in the way vfio used for fsl-mc bus
from the eal vfio.
- The scanning of bus for individual objects on the basis of
the DPRC container.
- The use and mapping of MC portal for object access
With the evolution of bus model, they can be further aligned with
eal vfio code.

This patch introduces the DPAA2 MC(Management complex Driver).
This is a minimal set of low level functions to send and
receive commands to the fsl-mc. It includes support for basic
management commands and commands to manipulate MC objects.
This is common to be used by various DPAA2 PMDs. e.g.net, crypto
and other drivers.
This is a low level library also used in kernel.

QBMAN, is a hardware block which interfaces with the other
accelerating hardware blocks (For e.g., WRIOP) on NXP's DPAA2
SoC for queue, buffer and packet scheduling.
This patch introduces a userspace driver for interfacing with
the QBMAN hw block.
The qbman-portal component provides APIs to do the low level
hardware bit twiddling for operations such as:
-initializing Qman software portals
-building and sending portal commands
-portal interrupt configuration and processing
This same/similar code is used in kernel and compat file is used
to make it working in user space.

When TSO is disabled we still have to calculate partial checksum if DF bit
if turned off. This is caused by firmware bug.
First of all, we must make sure that we are dealing with IPV4 packet.
If not, we will just skip further checking of this packet and move to
the next one.
If application will not set m2_len field, we assume we that it was Ethernet
frame because we have to look inside the packet to check for the DF flag.
To make it work properly, PMD is assuming that before sending
packet application called function rte_eth_tx_prepare().

In case of fail when refilling Rx descriptors, all additional mbufs

On RX path, after receiving bunch of packets, variable tracking
available descriptors in HW queue was not updated.
To fix this issue, variable tracking used descriptors must be updated
after receiving packets - it must be reduced by the amount of received
descriptors in current batch.
Additionally, variable next_to_clean in rx_ring must be updated before
entering ena_populate_rx_queue() to keep it up to date with the current
ring state.
