Thomas Monjalon ee76bddc76 doc: fix naming of Mellanox devices
The devices of the family ConnectX may have two letters as suffix.
Such suffix is preceded with a space and the second x is lowercase:
    - ConnectX-4 Lx
    - ConnectX-5 Ex
    - ConnectX-6 Dx

Uppercase of the device family name BlueField is also fixed.

The lists of supported devices are fixed.

Refer to the previous release notes for examples.
Suggested order in release notes items:
* Core libs (EAL, mempool, ring, mbuf, buses)
* Device abstraction libs and PMDs
- ethdev (lib, PMDs)
- cryptodev (lib, PMDs)
- eventdev (lib, PMDs)
- etc
* Other libs

=========================================================
* **Added support for freeing hugepages exactly as originally allocated.**
Some applications using memory event callbacks (especially for managing
RDMA memory regions) require that memory be freed back to the system
exactly as it was originally allocated. These applications typically
also require that a malloc allocation not span across two separate
hugepage allocations. A new ``--match-allocations`` EAL init flag has
been added to fulfill both of these requirements.
* **Added API to register external memory in DPDK.**
A new ``rte_extmem_register``/``rte_extmem_unregister`` API was added to allow
chunks of external memory to be registered with DPDK without adding them to
the malloc heap.
* **Added support for using virtio-user without hugepages.**
The ``--no-huge`` mode was augmented to use memfd-backed memory (on systems
that support memfd), to allow using virtio-user-based NICs without
hugepages.
* **Release of the ENA PMD v2.0.0.**
Version 2.0.0 of the ENA PMD was added with the following additions:
* Added Low Latency Queue v2 (LLQv2). This feature reduces the latency
of the packets by pushing the header directly through the PCI to the
device. This allows the NIC to start handle packets right after the doorbell
without waiting for DMA.
* Added independent configuration of HW Tx and Rx ring depths.
* Added support for up to 8k Rx descriptors per ring.
* Added additional doorbell check on Tx, to handle Tx more efficiently for big
bursts of packets.
* Added per queue statistics.
* Added extended statistics using xstats DPDK API.
* The reset routine was aligned with the DPDK API, so now it can be
handled as in other PMDs.
* Fixed out of order (OOO) completion.
* Fixed memory leaks due to port stops and starts in the middle of
traffic.
* Updated documentation and features list of the PMD.
* **Updated mlx5 driver.**
Updated the mlx5 driver including the following changes:
* Fixed ``imissed`` counter to be reported through ``rte_eth_stats`` instead
of ``rte_eth_xstats``.
* Added packet header modification through Direct Verbs flow driver.
* Added ConnectX-6 PCI device ID to be proved by ``mlx5`` driver.
* Added flow counter support to Direct Verbs flow driver though DevX.
* Renamed build options for the glue layer to
``CONFIG_RTE_IBVERBS_LINK_DLOPEN`` for make and ``ibverbs_link`` for meson.
* Added static linkage of ``mlx`` dependency.
* Improved stability of E-Switch flow driver.
* Added new make build configuration to set the cacheline size for BlueField
correctly - ``arm64-bluefield-linux-gcc``.
* **Updated the enic driver.**
* Added support for the ``RTE_ETH_DEV_CLOSE_REMOVE`` flag.
* Added a handler to get the firmware version string.
* Added support for multicast filtering.
* **Added dynamic queues allocation support for i40e VF.**
Previously, the available VF queues were reserved by PF at initialization
stage. Now both DPDK PF and Kernel PF (>=2.1.14) will support dynamic queue
allocation. At runtime, when VF requests for more queue exceed the initial
reserved amount, the PF can allocate up to 16 queues as the request after a
VF reset.
* **Added ICE net PMD.**
Added the new ``ice`` net driver for Intel(R) Ethernet Network Adapters E810.
See the :doc:`../nics/ice` NIC guide for more details on this new driver.
* **Added support for SW-assisted VDPA live migration.**
This SW-assisted VDPA live migration facility helps VDPA devices without
logging capability to perform live migration, a mediated SW relay can help
devices to track dirty pages caused by DMA. the IFC driver has enabled this
SW-assisted live migration mode.
* **Added security checks to the cryptodev symmetric session operations.**
Added a set of security checks to the access cryptodev symmetric session.
The checks include the session's user data read/write check and the
session private data referencing status check while freeing a session.
* **Updated the AESNI-MB PMD.**
* Added support for intel-ipsec-mb version 0.52.
* Added AES-GMAC algorithm support.
* Added Plain SHA1, SHA224, SHA256, SHA384, and SHA512 algorithms support.
* **Added IPsec Library.**
Added an experimental library ``librte_ipsec`` to provide ESP tunnel and
transport support for IPv4 and IPv6 packets.
The library provides support for AES-CBC ciphering and AES-CBC with HMAC-SHA1
algorithm-chaining, and AES-GCM and NULL algorithms only at present. It is
planned to add more algorithms in future releases.
See :doc:`../prog_guide/ipsec_lib` for more information.
* **Updated the ipsec-secgw sample application.**
The ``ipsec-secgw`` sample application has been updated to use the new
``librte_ipsec`` library, which has also been added in this release.
The original functionality of ipsec-secgw is retained, a new command line
parameter ``-l`` has been added to ipsec-secgw to use the IPsec library,
instead of the existing IPsec code in the application.
The IPsec library does not support all the functionality of the existing
ipsec-secgw application. It is planned to add the outstanding functionality
in future releases.
See :doc:`../sample_app_ug/ipsec_secgw` for more information.
* **Enabled checksum support in the ISA-L compressdev driver.**
Added support for both adler and crc32 checksums in the ISA-L PMD.
This aids data integrity across both compression and decompression.
* **Added a compression performance test tool.**
Added a new performance test tool to test the compressdev PMD. The tool tests
compression ratio and compression throughput.
* **Added intel_pstate support to Power Management library.**
Previously, using the power management library required the
disabling of the intel_pstate kernel driver, and the enabling of the
acpi_cpufreq kernel driver. This is no longer the case, as the use of
the intel_pstate kernel driver is now supported, and automatically
detected by the library.
API Changes
-----------
.. This section should contain API changes. Sample format:
* sample: Add a short 1-2 sentence description of the API change
which was announced in the previous releases and made in this release.
Start with a scope label like "ethdev:".
Use fixed width quotes for ``function_names`` or ``struct_names``.
Use the past tense.
This section is a comment. Do not overwrite or remove it.
Also, make sure to start the actual text at the margin.
=========================================================
* eal: Function ``rte_bsf64`` in ``rte_bitmap.h`` has been renamed to
``rte_bsf64_safe`` and moved to ``rte_common.h``. A new ``rte_bsf64``
function has been added in ``rte_common.h`` that follows the convention set
by the existing ``rte_bsf32`` function.
* eal: Segment fd API on Linux now sets error code to ``ENOTSUP`` in more cases
where segment the fd API is not expected to be supported:
- On attempt to get a segment fd for an externally allocated memory segment
- In cases where memfd support would have been required to provide segment
fds (such as in-memory or no-huge mode)
* eal: Functions ``rte_malloc_dump_stats()``, ``rte_malloc_dump_heaps()`` and
``rte_malloc_get_socket_stats()`` are no longer safe to call concurrently with
``rte_malloc_heap_create()`` or ``rte_malloc_heap_destroy()`` function calls.
* mbuf: ``RTE_MBUF_INDIRECT()``, which was deprecated in 18.05, was replaced
with ``RTE_MBUF_CLONED()`` and removed in 19.02.
* sched: As result of the new format of the mbuf sched field, the
functions ``rte_sched_port_pkt_write()`` and
``rte_sched_port_pkt_read_tree_path()`` got an additional parameter of
type ``struct rte_sched_port``.
* pdump: The ``rte_pdump_set_socket_dir()``, the parameter ``path`` of
``rte_pdump_init()`` and enum ``rte_pdump_socktype`` were deprecated
since 18.05 and are removed in this release.
* cryptodev: The parameter ``session_pool`` in the function
``rte_cryptodev_queue_pair_setup()`` is removed.
* cryptodev: a new function ``rte_cryptodev_sym_session_pool_create()`` has been
introduced. This function is now mandatory when creating symmetric session
header mempool. Please note all crypto applications are required to use this
function from now on. Failed to do so will cause a
``rte_cryptodev_sym_session_create()`` function call return error.
ABI Changes
-----------
.. This section should contain ABI changes. Sample format:
* sample: Add a short 1-2 sentence description of the ABI change
which was announced in the previous releases and made in this release.
Start with a scope label like "ethdev:".
Use fixed width quotes for ``function_names`` or ``struct_names``.
Use the past tense.
This section is a comment. Do not overwrite or remove it.
Also, make sure to start the actual text at the margin.
=========================================================
* mbuf: The format of the sched field of ``rte_mbuf`` has been changed
to include the following fields: ``queue ID``, ``traffic class``, ``color``.
* cryptodev: as shown in the 18.11 deprecation notice, the structure
``rte_cryptodev_qp_conf`` has added two parameters for symmetric session
mempool and symmetric session private data mempool.
* cryptodev: as shown in the 18.11 deprecation notice, the structure
``rte_cryptodev_sym_session`` has been updated to contain more information
to ensure safely accessing the session and session private data.
* security: A new field ``uint64_t opaque_data`` has been added to
``rte_security_session`` structure. That would allow upper layer to easily
associate/de-associate some user defined data with the security session.

Known Issues
------------
.. This section should contain new known issues in this release. Sample format:
* **Add title in present tense with full stop.**
Add a short 1-2 sentence description of the known issue
in the present tense. Add information on any known workarounds.
This section is a comment. Do not overwrite or remove it.
Also, make sure to start the actual text at the margin.
=========================================================
* ``AVX-512`` support has been disabled for ``GCC`` builds when ``binutils 2.30``
is detected [1] because of a crash [2]. This can affect ``native`` machine type
build targets on the platforms that support ``AVX512F`` like ``Intel Skylake``
processors, and can cause a possible performance drop. The immediate workaround
is to use ``clang`` compiler on these platforms.
Initial workaround in DPDK v18.11 was to disable ``AVX-512`` support for ``GCC``
completely, but based on information on defect submitted to GCC community [3],
issue has been identified as ``binutils 2.30`` issue. Since currently only GCC
generates ``AVX-512`` instructions, the scope is limited to ``GCC`` and
``binutils 2.30``
