fdab8f2e17 version: 21.11-rc0
Start a new release cycle with empty release notes.

The ABI version becomes 22.0.
The map files are updated to the new ABI major number (22).
The ABI exceptions are dropped and CI ABI checks are disabled because
compatibility is not preserved.

6afc4baf4f eal: use callbacks for power monitoring comparison
Previously, the semantics of power monitor were such that we were
checking current value against the expected value, and if they matched,
then the sleep was aborted. This is somewhat inflexible, because it only
allowed us to check for a specific value in a specific way.

This commit replaces the comparison with a user callback mechanism, so
that any PMD (or other code) using `rte_power_monitor()` can define
their own comparison semantics and decision making on how to detect the
need to abort the entering of power optimized state.

Existing implementations are adjusted to follow the new semantics.

fcc5489c18 event/dlb2: select scalar dequeue by default
Optimized dequeue using x86 vector instructions was added
in 21.05, but due to limited testing the default has been
changed back to the scalar mode implementation. The vector mode
implementation can be enabled via the devargs option
"vector_opts_enabled=<y/Y>".

eeded2044a log: register with standardized names
Let's try to enforce the convention where most drivers use a pmd. logtype
with their class reflected in it, and libraries use a lib. logtype.

Introduce two new macros:
- RTE_LOG_REGISTER_DEFAULT can be used when a single logtype is
  used in a component. It is associated to the default name provided
  by the build system,
- RTE_LOG_REGISTER_SUFFIX can be used when multiple logtypes are used,
  and then the passed name is appended to the default name,

RTE_LOG_REGISTER is left untouched for existing external users
and for components that do not comply with the convention.

There is a new Meson variable log_prefix to adapt the default name
for baseband (pmd.bb.), bus (no pmd.) and mempool (no pmd.) classes.

Note: achieved with below commands + reverted change on net/bonding +
edits on crypto/virtio, compress/mlx5, regex/mlx5

037a616762 event/dlb2: use new implementation of HW types header
As support for DLB v2.5 was added, modifications were made to
dlb_hw_types_new.h, but the old file needed to be preserved during
the port in order to meet the requirement that individual patches in
a series each compile successfully. Since the DLB v2.5 support is
completely integrated, it is now safe to remove the old (original)
file, as well as the DLB2_USE_NEW_HEADERS define that was used to
control which version of the file was to be included in certain
source files.
It is now safe to rename the new file, and use it unconditionally
in all DLB source files.

0d65f8f9e3 event/dlb2: add v2.5 HW init
Add support for DLB v2.5 probe-time hardware init,
and sets up a framework for incorporating the remaining
changes required to support DLB v2.5.

DLB v2.0 and DLB v2.5 are similar in many respects, but their
register offsets and definitions are different. As a result of these,
differences, the low level hardware functions must take the device
version into consideration. This requires that the hardware version be
passed to many of the low level functions, so that the PMD can
take the appropriate action based on the device version.

To ease the transition and keep the individual patches small, three
temporary files are added in this commit. These files have "new"
in their names.  The files with "new" contain changes specific to a
consolidated PMD that supports both DLB v2.0 and DLB 2.5. Their sister
files of the same name (minus "new") contain the old DLB v2.0 specific
code. The intent is to remove code from the original files as that code
is ported to the combined DLB 2.0/2.5 PMD model and added to the "new"
files in a series of commits. At end of the patch series, the old files
will be empty and the "new" files will have the logic needed
to implement a single PMD that supports both DLB v2.0 and DLB v2.5.
At that time, the original DLB v2.0 specific files will be deleted,
and the "new" files will be renamed and replace them.

Removing PAGE_SIZE definitions will fix dlb drivers for musl libc,

DLB does not support reconfiguring individual queues
or ports on the fly. The entire device must be reconfigured.
Previously allocated port QE and memzone memory
is freed in this patch.

c667583d82 event/dlb2: add token pop API
The PMD uses a public interface to allow applications to
control the token pop mode. Supported token pop modes are
as follows, and they impact core scheduling affinity for
ldb ports.

AUTO_POP: Pop the CQ tokens immediately after dequeueing.
DELAYED_POP: Pop CQ tokens after (dequeue_depth - 1) events
             are released. Supported on load-balanced ports
             only.
DEFERRED_POP: Pop the CQ tokens during next dequeue operation.

a2e4f1f5e7 event/dlb2: add dequeue and its burst variants
Add support for dequeue, dequeue_burst, ...

DLB2 does not currently support interrupts, but instead use
umonitor/umwait if supported by the processor. This allows
the software to monitor and wait on writes to a cache-line.

DLB2 supports normal and sparse cq mode. In normal mode the
hardware will pack 4 QEs into each cache line. In sparse cq
mode, the hardware will only populate one QE per cache line.
Software must be aware of the cq mode, and take the appropriate
actions, based on the mode.

59e1a966ea event/dlb2: add eventdev start
Add support for the eventdev start entry point.
We delay initializing some resources until
eventdev start, since the number of linked queues can be
used to determine if we are dealing with a ldb or dir resource.
If this is a device restart, then the previous configuration
will be reapplied.
