Jerin Jacob 33e71acf3d drivers: remove octeontx2 drivers 
As per the deprecation notice,  In the view of enabling unified driver
for octeontx2(cn9k)/octeontx3(cn10k), removing drivers/octeontx2
drivers and replace with drivers/cnxk/ which
supports both octeontx2(cn9k) and octeontx3(cn10k) SoCs.

This patch does the following

- Replace drivers/common/octeontx2/ with drivers/common/cnxk/
- Replace drivers/mempool/octeontx2/ with drivers/mempool/cnxk/
- Replace drivers/net/octeontx2/ with drivers/net/cnxk/

DPDK Release 19.08
==================
New Features
------------
* **EAL will now pick IOVA as VA mode as the default in most cases.**
Previously, the preferred default IOVA mode was selected to be IOVA as PA. The
behavior has now been changed to handle IOVA mode detection in a more complex
manner, and will default to IOVA as VA in most cases.
* **Added MCS lock.**
MCS lock provides scalability by spinning on a CPU/thread local variable
which avoids expensive cache bouncing.
It provides fairness by maintaining a list of acquirers and passing
the lock to each CPU/thread in the order they acquired the lock.
* **Updated the EAL Pseudo-random Number Generator.**
The ``lrand48()`` based ``rte_rand()`` function is replaced with a
DPDK-native combined Linear Feedback Shift Register (LFSR)
pseudo-random number generator (PRNG).
This new PRNG implementation is multi-thread safe, provides
higher-quality pseudo-random numbers (including full 64 bit
support) and improved performance.
In addition, ``<rte_random.h>`` is extended with a new function
``rte_rand_max()`` which supplies unbiased, bounded pseudo-random
numbers.
* **Updated the Broadcom bnxt PMD.**
Updated the Broadcom bnxt PMD. The major enhancements include:
* Performance optimizations in non-vector Tx path.
* Added support for SSE vector mode.
* Updated HWRM API to version 1.10.0.91.
* **Added support for Broadcom NetXtreme-E BCM57500 Ethernet controllers.**
Added support to the Broadcom bnxt PMD for the BCM57500 (a.k.a. "Thor") family
of Ethernet controllers. These controllers support link speeds up to
200Gbps, 50G PAM-4, and PCIe 4.0.
* **Added Huawei hinic PMD.**
Added the new ``hinic`` net driver for Huawei Intelligent PCIE Network
Adapters based on the Huawei Ethernet Controller Hi1822.
See the :doc:`../nics/hinic` guide for more details on this new driver.

* Added support for Rx interrupts.
* **Added memif PMD.**
Added a new Shared Memory Packet Interface (``memif``) PMD.
See the :doc:`../nics/memif` guide for more details on this new driver.
* **Updated the AF_XDP PMD.**
Updated the AF_XDP PMD. The new features include:
* Enabled zero copy through mbuf's external memory mechanism to achieve
higher performance.
* Added multi-queue support to allow one af_xdp vdev with multiple netdev
queues.
* Enabled "need_wakeup" feature which can provide efficient support for the
use case where the application and driver executing on the same core.
* **Enabled infinite Rx in the PCAP PMD.**
Added an infinite Rx feature to the PCAP PMD which allows packets in the Rx
PCAP to be received repeatedly at a high rate. This can be useful for quick
performance testing of DPDK apps.
* **Enabled receiving no packet in the PCAP PMD.**
Added function to allow users to run the PCAP PMD without receiving any
packets on PCAP Rx. When the function is called, a dummy queue is created
for each Tx queue argument passed.
* **Added a FPGA_LTE_FEC bbdev PMD.**
Added a new ``fpga_lte_fec`` bbdev driver for the Intel\ |reg| FPGA PAC
(Programmable Acceleration Card) N3000. See the
:doc:`../bbdevs/fpga_lte_fec` BBDEV guide for more details on this new driver.
* **Updated the TURBO_SW bbdev PMD.**

* ``eventdevs/octeontx2``
* ``rawdevs/octeontx2_dma``
* **Introduced the Intel NTB PMD.**
Added a PMD for Intel NTB (Non-transparent Bridge). This PMD implements
a handshake between two separate hosts and can share local memory for peer
host to directly access.
* **Updated the IPSec library and IPsec Security Gateway application.**
Added the following features to ``librte_ipsec``. Corresponding changes are
also added in the ``ipsec-secgw`` sample application.
* ECN and DSCP field header reconstruction as per RFC4301.

Added a multiple cores feature to the compression perf tool application.
Removed Items
-------------
* Removed KNI ethtool, ``CONFIG_RTE_KNI_KMOD_ETHTOOL``, support.
* build: armv8 crypto extension is disabled.
API Changes
-----------
* The ``rte_mem_config`` structure has been made private. New accessor
``rte_mcfg_*`` functions were introduced to provide replacement for direct
access to the shared mem config.
* The network structures, definitions and functions have
been prefixed by ``rte_`` to resolve conflicts with libc headers.
* malloc: The function ``rte_malloc_set_limit()`` was never implemented.
It is deprecated and will be removed in a future release.
* cryptodev: the ``uint8_t *data`` member of the ``key`` structure in the xforms
structure (``rte_crypto_cipher_xform``, ``rte_crypto_auth_xform``, and
``rte_crypto_aead_xform``) have been changed to ``const uint8_t *data``.
* eventdev: No longer marked as experimental.
The eventdev functions are no longer marked as experimental, and have
become part of the normal DPDK API and ABI. Any future ABI changes will be
announced at least one release before the ABI change is made. There are no
ABI breaking changes planned.
* ip_frag: The IP fragmentation library converts input mbuf into fragments
using input MTU size via the ``rte_ipv4_fragment_packet()`` interface.
Once fragmentation is done, each ``mbuf->ol_flags`` are set to enable IP
checksum H/W offload irrespective of the platform capability.
Cleared IP checksum H/W offload flag from the library. The application must
set this flag if it is supported by the platform and application wishes to
use it.
* ip_frag: IP reassembly library converts the list of fragments into a
reassembled packet via ``rte_ipv4_frag_reassemble_packet()`` interface.
Once reassembly is done, ``mbuf->ol_flags`` are set to enable IP checksum H/W
offload irrespective of the platform capability. Cleared IP checksum H/W
offload flag from the library. The application must set this flag if it is
supported by the platform and application wishes to use it.
* sched: Macros ``RTE_SCHED_QUEUES_PER_TRAFFIC_CLASS`` and
``RTE_SCHED_PIPE_PROFILES_PER_PORT`` are removed for flexible configuration
of pipe traffic classes and their queues size, and for runtime configuration
of the maximum number of pipe profiles, respectively. In addition, the
``wrr_weights`` field of struct ``rte_sched_pipe_params`` is modified to be
used only for best-effort tc, and the ``qsize`` field of struct
``rte_sched_port_params`` is changed to allow different sizes for each
queue.
ABI Changes
-----------
* eventdev: Event based Rx adapter callback
The mbuf pointer array in the event eth Rx adapter callback
has been replaced with an event array. Using
an event array allows the application to change attributes
of the events enqueued by the SW adapter.
The callback can drop packets and populate
a callback argument with the number of dropped packets.
Add a Rx adapter stats field to keep track of the total
number of dropped packets.
* cryptodev: New member in ``rte_cryptodev_config`` to allow applications to
disable features supported by the crypto device. Only the following features
would be allowed to be disabled this way,
- ``RTE_CRYPTODEV_FF_SYMMETRIC_CRYPTO``.
- ``RTE_CRYPTODEV_FF_ASYMMETRIC_CRYPTO``.
- ``RTE_CRYPTODEV_FF_SECURITY``.
Disabling unused features would facilitate efficient usage of HW/SW offload.
* bbdev: New operations and parameters have been added to support new 5GNR
operations. The bbdev ABI is still kept experimental.
* rawdev: The driver names have been changed to ``librte_rawdev_*``.
Now they all have the same prefix, and same name with make and meson builds.

Known Issues
------------
* **Unsuitable IOVA mode may be picked as the default.**
Not all kernel drivers and not all devices support all IOVA modes. EAL will
attempt to pick a reasonable default based on a number of factors, but
there may be cases where the default is unsuitable.
It is recommended to use the `--iova-mode` command-line parameter if the
default is not suitable.
