4f86c0ba19 version: 20.11-rc0
Start a new release cycle with empty release notes.

The ABI version becomes 21.0.
The ABI major is back to normal, having only one number (21 vs 20.0).
The map files are updated to the new ABI major number (21).
The ABI exceptions are dropped.
Travis ABI check is disabled because compatibility is not preserved.

e0a439466b eal/linux: use C11 atomics for interrupt status
The event status is defined as a volatile variable and shared between
threads. Use C11 atomic built-ins with explicit ordering instead of
rte_atomic ops which enforce unnecessary barriers on aarch64.

The event status has been cleaned up by the compare-and-swap operation
when we free the event data, so there is no need to set it to invalid
after that.

7762e0139b build: remove special versioning for non stable libraries
Having a special versioning for experimental/internal libraries put a
additional maintenance cost while this status is already announced in
MAINTAINERS and the library headers/documentation.
Following discussions and vote at 05/20 TB meeting [1], use a single
versioning for all libraries in DPDK.

Note: for the ABI check, an exception [2] had been added when tweaking
this special versioning [3].
Prefer explicit libabigail rules (which will be dropped in 20.11).

64c563f8b1 common/mlx5: mark internal symbols
Move mlx5 symbols in the map file to the INTERNAL section and add
__internal tags to their definitions.
Those symbols were exported in 20.02 and now (20.05) they are removed.
Avoid ABI comparison issues between 20.05/20.08 and 20.02 by adding the
suppress_file directive to libabigail.abignore file. This directive will
prevent loading mlx5 common symbols and no comparison will be performed.

In addition move symbols from the EXPERIMENTAL section to the INTERNAL
section.

a0f0de06d4 cryptodev: fix ABI compatibility for ChaCha20-Poly1305
This patch adds versioned function rte_cryptodev_info_get()
to prevent some issues with ABI policy.
Node v21 works in same way as before, returning driver capabilities
directly to the API caller. These capabilities may include new elements
not part of the v20 ABI.
Node v20 function maintains compatibility with v20 ABI releases
by stripping out elements not supported in v20 ABI. Because
rte_cryptodev_info_get is called by other API functions,
rte_cryptodev_sym_capability_get function is versioned the same way.

105f3039c7 version: reference next ABI 21 for recent additions
Change references to ABI 20.0.1 to use ABI v21, see
https://doc.dpdk.org/guides/contributing/abi_policy.html#general-guidelines

"Major ABI versions are declared no more frequently than yearly.
Compatibility with the major ABI version is mandatory in subsequent
releases until a new major ABI version is declared."

Combined ABI policy and versioning in maintainers, add map files to the
filter to more closely monitor future ABI changes.

44bf3c796b ethdev: support flow aging
One of the reasons to destroy a flow is the fact that no packet matches
the flow for "timeout" time.
For example, when TCP\UDP sessions are suddenly closed.

Currently, there is not any DPDK mechanism for flow aging and the
applications use their own ways to detect and destroy aged-out flows.

The flow aging implementation need include:
- A new rte_flow action: RTE_FLOW_ACTION_TYPE_AGE to set the timeout and
  the application flow context for each flow.
- A new ethdev event: RTE_ETH_EVENT_FLOW_AGED for the driver to report
  that there are new aged-out flows.
- A new rte_flow API: rte_flow_get_aged_flows to get the aged-out flows
  contexts from the port.
- Support input flow aging command line in Testpmd.

The new event type addition in the enum is flagged as an ABI breakage,
so an ignore rule is added for these reasons:
- It is not changing value of existing types (except MAX)
- The new value is not used by existing API if the event is not
  registered
In general, it is safe adding new ethdev event types at the end of the
enum, because of event callback registration mechanism.

e6ba4731c0 ring: introduce RTS ring mode
Introduce relaxed tail sync (RTS) mode for MT ring synchronization.
Aim to reduce stall times in case when ring is used on
overcommited cpus (multiple active threads on the same cpu).
The main difference from original MP/MC algorithm is that
tail value is increased not by every thread that finished enqueue/dequeue,
but only by the last one.
That allows threads to avoid spinning on ring tail value,
leaving actual tail value change to the last thread in the update queue.

777014e56d devtools: add ABI checks
For normal developers, those checks are disabled.

Enabling them requires a configuration that will trigger the ABI dumps
generation as part of the existing devtools/test-build.sh and
devtools/test-meson-builds.sh scripts.

Those checks are enabled in the CI for the default meson options on x86
and aarch64 so that proposed patches are validated via our CI robot.
A cache of the ABI is stored in travis jobs to avoid rebuilding too
often.

Checks can be informational only, by setting ABI_CHECKS_WARN_ONLY when
breaking the ABI in a future release.

Explicit suppression rules have been added on internal structures
exposed to crypto drivers as the current ABI policy does not apply to
them.
This could be improved in the future by carefully splitting the headers
content with application and driver "users" in mind.

We currently have issues reported for librte_crypto recent changes for
which suppression rules have been added too.

Mellanox glue libraries are explicitly skipped as they are not part of
the application ABI.
