At device probe, the fslmc bus driver calls rte_vfio_get_group_fd() to
get a fd associated to a vfio group. This function first checks if the
group is already opened, else it opens /dev/vfio/%u, and increases the
number of active groups in default_vfio_cfg (which references the
default vfio container).
When adding the first group to a vfio_cfg, the caller is supposed to
pick an IOMMU type and set up DMA mappings for container, as it's done
by pci bus, but it is not done here. Instead, a new container is created
and used.
This prevents the pci bus driver, which uses the default_vfio_cfg
container, to configure the container because
default_vfio_cfg->active_group > 1.
This patch fixes the issue by always creating a new container (and its
associated vfio_cfg) and binding the group to it.

The symbols which are not listed in the version script

Adding a local section with a wildcard make non-listed functions
and variables as hidden, as it should be in all version.map files.
These are the changes done in the shared libraries:
- DF .text Base auxiliary_add_device
- DF .text Base auxiliary_dev_exists
- DF .text Base auxiliary_dev_iterate
- DF .text Base auxiliary_insert_device
- DF .text Base auxiliary_is_ignored_device

- DF .text Base auxiliary_on_scan
- DF .text Base auxiliary_scan
- DO .bss Base auxiliary_bus_logtype
- DO .data Base auxiliary_bus
- DO .bss Base gpu_logtype
There is no impact on regexdev library.
Because these local symbols were exported as non-internal
in DPDK 21.11, any change in these functions would break the ABI.
Exception rules are added for these experimental libraries,
so the ABI check will skip them until the next ABI version.
A check is added to avoid such miss in future.

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.

If devargs_parse not implemented by bus driver, the new syntax parser
rte_devargs_layers_parse default will resolve devargs name from bus's

Different bus driver might choose different keys from arguments with
