As described in [1] and as announced in [2], The field ``dataunit_len``
of the ``struct rte_crypto_cipher_xform`` moved to the end of the
structure and extended to ``uint32_t``.
In this way, sizes bigger than 64K bytes can be supported for data-unit
lengths.

As reported by Dmitry, RTE_MEMPOOL_F_POOL_CREATED is a flag only
manipulated internally.
This flag is not supposed to be requested from an application and would
probably result in an incorrect behavior if an application did pass it.
At least one other internal flag has been added recently and more may be
introduced later.
Rework the check and export a mask of valid user flags for use in the
unit test.

Data path performance can benefit if the PMD knows which memory it will
need to handle in advance, before the first mbuf is sent to the PMD.
It is impractical, however, to consider all allocated memory for this
purpose. Most often mbuf memory comes from mempools that can come and
go. PMD can enumerate existing mempools on device start, but it also
needs to track creation and destruction of mempools after the forwarding
starts but before an mbuf from the new mempool is sent to the device.
Add an API to register callback for mempool life cycle events:
* rte_mempool_event_callback_register()
* rte_mempool_event_callback_unregister()
Currently tracked events are:
* RTE_MEMPOOL_EVENT_READY (after populating a mempool)
* RTE_MEMPOOL_EVENT_DESTROY (before freeing a mempool)
Provide a unit test for the new API.
The new API is internal, because it is primarily demanded by PMDs that
may need to deal with any mempools and do not control their creation,
while an application, on the other hand, knows which mempools it creates
and doesn't care about internal mempools PMDs might create.

Currently there are some public headers that include 'sys/queue.h', which
is not POSIX, but usually provided by the Linux/BSD system library.
(Not in POSIX.1, POSIX.1-2001, or POSIX.1-2008. Present on the BSDs.)
The file is missing on Windows. During the Windows build, DPDK uses a
bundled copy, so building a DPDK library works fine. But when OVS or other
applications use DPDK as a library, because some DPDK public headers
include 'sys/queue.h', on Windows, it triggers an error due to no such
file.
One solution is to install the 'lib/eal/windows/include/sys/queue.h' into
Windows environment, such as [1]. However, this means DPDK exports the
functionalities of 'sys/queue.h' into the environment, which might cause
symbols, macros, headers clashing with other applications.
The patch fixes it by removing the "#include <sys/queue.h>" from
DPDK public headers, so programs including DPDK headers don't depend
on the system to provide 'sys/queue.h'. When these public headers use
macros such as TAILQ_xxx, we replace it by the ones with RTE_ prefix.
For Windows, we copy the definitions from <sys/queue.h> to rte_os.h
in Windows EAL. Note that these RTE_ macros are compatible with
<sys/queue.h>, both at the level of API (to use with <sys/queue.h>
macros in C files) and ABI (to avoid breaking it).
Additionally, the TAILQ_FOREACH_SAFE is not part of <sys/queue.h>,
the patch replaces it with RTE_TAILQ_FOREACH_SAFE.

Add option to indicate whether outer header verification
need to be done as part of inbound IPsec processing.
With inline IPsec processing, SA lookup would be happening
in the Rx path of rte_ethdev. When rte_flow is configured to
support more than one SA, SPI would be used to lookup SA.
In such cases, additional verification would be required to
ensure duplicate SPIs are not getting processed in the inline path.
For lookaside cases, the same option can be used by application
to offload tunnel verification to the PMD.
These verifications would help in averting possible DoS attacks.

Windows EAL depends on some system libraries. They were linked using
add_project_link_arguments('-l<LIB>'), which prevented meson from adding
them to Libs.private of pkg-config file. As a result, applications using
pkg-config to find DPDK hit link errors, for example:
librte_eal.a(eal_windows_eal_debug.c.obj) : error LNK2019: unresolved

For device probe and iterator, devargs name was key information,
parsed by rte_devargs_parse. In legacy parser, devargs name was
extracted after bus name:
bus:name,kv_arguments,,,
Example:
pci:83:00.0,arguments,...
vdev:pcap0,...
To be compatible with legacy parser, this patch introduces new
bus driver API devargs_parse to parse devargs and update devargs name.
If devargs_parse not implemented by bus driver, the new syntax parser
rte_devargs_layers_parse default will resolve devargs name from bus's
"name" argument.
Different bus driver might choose different keys from arguments with
unified format. The PCI bus implementation fills the devargs name with
the "addr" argument, example:
-a bus=pci,addr=83:00.0/class=eth/driver=mlx5,...
name: 0000:03:00.0
-a bus=vdev,name=pcap0/class=eth/driver=pcap,...

The first argument to rte_bsf32_safe was incorrectly declared as

function rte_bsf32 only accepts 32 bit values. This was a mistake
introduced when the safe version was added and probably cause
by copy/paste from the 64 bit version.
The bug passed silently under the radar until some other code was
built with -Wall and -Wextra in C++ and C++ complains about the
missing cast.
Yes, this is a API signature change, but the original code was wrong.
It is an inline so not an ABI change.
