Tyler Retzlaff 4b81c145ae eal: change return type of bsf/fls functions
The function return type is changed to fixed width uint32_t
to be consistent with what appears to be the original authors intent.
It doesn't make much sense to return signed integers for these functions.

The description should be enough to allow someone scanning
the release notes to understand the new feature.
If the feature adds a lot of sub-features you can use a bullet list
like this:
* Added feature foo to do something.

=======================================================
* eal: RTE_FUNC_PTR_OR_* macros have been marked deprecated and will be removed
in the future. Applications can use ``devtools/cocci/func_or_ret.cocci``
to update their code.
* eal: Updated ``rte_eal_remote_launch`` so it returns -EPIPE in case of
a read or write error on the pipe, instead of calling ``rte_panic``.
* eal: Updated return types for rte_{bsf,fls} inline functions
to be consistently ``uint32_t``.
* mempool: Deprecated helper macro ``MEMPOOL_HEADER_SIZE()`` is removed.
The replacement macro ``RTE_MEMPOOL_HEADER_SIZE()`` is internal only.
* mempool: Deprecated macro to register mempool driver
``MEMPOOL_REGISTER_OPS()`` is removed. Use replacement macro
``RTE_MEMPOOL_REGISTER_OPS()`` instead.
* mempool: Deprecated macros ``MEMPOOL_PG_NUM_DEFAULT`` and
``MEMPOOL_PG_SHIFT_MAX`` are removed. These macros are not used and
not required any more.
* mbuf: Removed deprecated ``PKT_*`` flags.
Use corresponding flags with ``RTE_MBUF_F_`` prefix instead.
Application can use ``devtools/cocci/prefix_mbuf_offload_flags.cocci``
to replace all occurrences of old mbuf flags in C code.
* bus: Registering a bus has been marked as an internal API.
External users may still register their bus using the ``bus_driver.h``
driver header (see ``enable_driver_sdk`` meson option).
The ``rte_bus`` object is now opaque and must be manipulated through added
accessors.
* drivers: Registering a driver on the ``auxiliary``, ``ifpga``, ``pci``,
``vdev``, ``vmbus`` buses has been marked as an internal API.
External users may still register their driver using the associated driver
headers (see ``enable_driver_sdk`` meson option).
The ``rte_driver`` and ``rte_device`` objects are now opaque and must be
manipulated through added accessors.
* ethdev: Removed deprecated macros. Applications can use ``devtools/cocci/namespace_ethdev.cocci``
to update their code.
* Removed deprecated ``ETH_LINK_SPEED_*``, ``ETH_SPEED_NUM_*`` and ``ETH_LINK_*``
(duplex-related) defines. Use corresponding defines with ``RTE_`` prefix
instead.
* Removed deprecated ``ETH_MQ_RX_*`` and ``ETH_MQ_TX_*`` defines.
Use corresponding defines with ``RTE_`` prefix instead.
* Removed deprecated ``ETH_RSS_*`` defines for hash function and
RETA size specification. Use corresponding defines with ``RTE_`` prefix
instead.
* Removed deprecated ``DEV_RX_OFFLOAD_*`` and ``DEV_TX_OFFLOAD_``
defines. Use corresponding defines with ``RTE_ETH_RX_OFFLOAD_`` and
``RTE_ETH_TX_OFFLOAD_`` prefix instead.
* Removed deprecated ``ETH_DCB_*``, ``ETH_VMDQ_``, ``ETH_*_TCS``,
``ETH_*_POOLS`` and ``ETH_MAX_VMDQ_POOL`` defines. Use corresponding
defines with ``RTE_`` prefix instead.
* Removed deprecated ``RTE_TUNNEL_*`` defines. Use corresponding
defines with ``RTE_ETH_TUNNEL_`` prefix instead.
* Removed deprecated ``RTE_FC_*`` defines. Use corresponding
defines with ``RTE_ETH_FC_`` prefix instead.
* Removed deprecated ``ETH_VLAN_*`` and ``ETH_QINQ_`` defines.
Use corresponding defines with ``RTE_`` prefix instead.
* Removed deprecated ``ETH_NUM_RECEIVE_MAC_ADDR`` define.
Use corresponding define with ``RTE_`` prefix instead.
* Removed deprecated ``PKT_{R,T}X_DYNF_METADATA`` defines.
Use corresponding defines ``RTE_MBUF_DYNFLAG_{R,T}X_METADATA`` instead.
* ethdev: Removed deprecated Flow Director configuration from device
configuration (``dev_conf.fdir_conf``). Moved corresponding structures
to internal API since some drivers still use it internally.
* ethdev: Promoted ``rte_eth_rx_metadata_negotiate()``
from experimental to stable.
* ethdev: Promoted the following flow primitives
from experimental to stable:
- ``RTE_FLOW_ACTION_TYPE_PORT_REPRESENTOR``
- ``RTE_FLOW_ACTION_TYPE_REPRESENTED_PORT``
- ``RTE_FLOW_ITEM_TYPE_PORT_REPRESENTOR``
- ``RTE_FLOW_ITEM_TYPE_REPRESENTED_PORT``
* ethdev: Promoted ``rte_flow_pick_transfer_proxy()``
from experimental to stable.
* cryptodev: The structure ``rte_cryptodev_sym_session`` was made internal.
The API ``rte_cryptodev_sym_session_init`` and ``rte_cryptodev_sym_session_clear``
were removed and user would only need to call ``rte_cryptodev_sym_session_create``
and ``rte_cryptodev_sym_session_free`` to create/destroy sessions.
The API ``rte_cryptodev_sym_session_create`` was updated to take a single mempool
with element size big enough to hold session data and session private data.
All sample applications were updated to attach an opaque pointer for the session
to the ``rte_crypto_op`` while enqueuing.
* security: The structure ``rte_security_session`` was made internal
and corresponding functions were updated to take/return an opaque session pointer.
The API ``rte_security_session_create`` was updated to take only one mempool
which has enough space to hold session and driver private data.
* security: MACsec support is added which resulted in updates
to structures ``rte_security_macsec_xform``, ``rte_security_macsec_stats``
and security capability structure ``rte_security_capability``
to accommodate MACsec capabilities.
* security: The experimental API ``rte_security_get_userdata`` was being unused
by most of the drivers and it was retrieving userdata from mbuf dynamic field.
The API is now removed and the application can directly get the userdata from
mbuf dynamic field.
* eventdev: The function ``rte_event_crypto_adapter_queue_pair_add`` was updated
to accept configuration of type ``rte_event_crypto_adapter_queue_conf``
instead of ``rte_event``,
similar to ``rte_event_eth_rx_adapter_queue_add`` signature.
Event will be one of the configuration fields,
together with additional vector parameters.
* metrics: Updated ``rte_metrics_init`` so it returns an error code instead
of calling ``rte_exit``.
* telemetry: The allowed characters in names for dictionary values
are now limited to alphanumeric characters and a small subset of additional
printable characters.
This will ensure that all dictionary parameter names can be output
without escaping in JSON - or in any future output format used.
Names for the telemetry commands are now similarly limited.
The parameters for telemetry commands are unaffected by this change.
* raw/ifgpa: The function ``rte_pmd_ifpga_get_pci_bus`` has been removed.
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.

=======================================================
* eal: Updated EAL thread names from ``lcore-worker-<lcore_id>`` to
``rte-worker-<lcore_id>`` so that DPDK can accommodate lcores higher than 99.
* ethdev: enum ``RTE_FLOW_ITEM`` was affected by deprecation procedure.
* ethdev: enum ``RTE_FLOW_ACTION`` was affected by deprecation procedure.
* eventdev: Added ``evtim_drop_count`` field
