acec04c4b2 build: disable experimental API check internally
Remove setting ALLOW_EXPERIMENTAL_API individually for each Makefile and
meson.build. Instead, enable ALLOW_EXPERIMENTAL_API flag across app, lib
and drivers.
This changes reduces the clutter across the project while still
maintaining the functionality of ALLOW_EXPERIMENTAL_API i.e. warning
external applications about experimental API usage.

e21492a517 net/mlx: fix overlinking with meson and glue dlopen
If ibverbs_link is dlopen, the PMD and application should not
be linked with ibverbs, but the glue library is.
Unfortunately the ibverbs dependency was exported in the
variable ext_deps, so there were overlinking.

It is fixed by not exporting the dependency in ext_deps,
and recreating a limited dependency object for cflags only.

af331158f2 net/mlx: workaround static linkage with meson
If ibverbs_link is static and the application choose to link DPDK
as static libraries, both PMD and ibverbs libraries must be linked
as static libraries. And the dependencies of ibverbs (netlink) must
still be linked as shared libraries.

Unfortunately, meson forget about the static requirement for ibverbs
when generating the .pc file.
As a result, libibverbs, libmlx4, libmlx5 are listed in Requires.private
section (allowing to be linked as shared libraries) and libnl is missing.

A fix is in progress for meson, but anyway we will have to live without
such a fix until a better version of meson is widely available:
	https://github.com/mesonbuild/meson/pull/6393

In order to avoid meson suggesting shared libraries in the section
Requires.private of the .pc file, the dependency object is recreated
with declare_dependency():
	- cflags are extracted the libibverbs.pc
	- ldflags, from libibverbs.pc, are processed to force
	static flavor of ibverbs libraries, thanks to this syntax:
			-l:libfoo.a

6affeabaf3 net/mlx: add static ibverbs linkage with meson
The libibverbs (and libmlx4/5) can be statically embedded
in the shared PMD library, or in the application with the static PMD.
It was supported with make build system in
commit 2c0dd7b69fb0 ("config: add static linkage of mlx dependency").

The same feature is enabled with meson when using pkg-config
(i.e. only if the call to dependency() is successful).
The fallback method for searching library with cc.find_library()
is not supported because the dependencies of the found library
would not be linked (no such info in .a file unlike .so).

The main difference, in meson build system, is the generated .pc file
giving arguments to link DPDK with the application.
Unfortunately the .pc file will not keep memory of the static linkage
option for libibverbs.

b4bf22d173 net/octeontx2: change default RSS hash calculation
Before C0 HW revision, The RSS adder was computed based the following
static formula.

rss_adder<7:0> = flow_tag<7:0> ^ flow_tag<15:8> ^
flow_tag<23:16> ^ flow_tag<31:24>

The above scheme has the following drawbacks:
1) It is not in line with other standard NIC behavior.
2) There can be an SW use case where SW can compute the hash
upfront using Toeplitz function and predict the queue selection
to optimize some packet lookup function. The nonstandard
way of doing XOR makes the consumer to not predict the queue selection.

C0 HW revision onward, The HW can configure the
rss_adder<7:0> as flow_tag<7:0> to align with standard NICs.

This patch adds an option to select legacy RSS adder mode
using tag_as_xor=1 devargs option while keeping the standard NIC
behavior as default.

One case is that any mlx5 vDPA device can be probed by both net/mlx5
and vdpa/mlx5.

Add a new mlx5 common API to get the requested driver by devargs:
class=[net/vdpa].

Skip net/mlx5 PMD probing while the device is selected to be probed by
the vDPA driver.

15c3807e86 common/mlx5: support DevX QP operations
QP creation is needed for vDPA virtq support.

Add 2 DevX commands to create QP and to modify QP state.

The support is for RC QP only in force loopback address mode.

By this way, the packets can be sent to other inernal destinations in
the nic. For example: other QPs or virtqs.

8712c80afe common/mlx5: add DevX virtq commands
Virtio emulation offload allows SW to offload the I/O operations of a
virtio virtqueue, using the device, allowing an improved performance
for its users.
While supplying all the relevant Virtqueue information (type, size,
memory location, doorbell information, etc.). The device can then
offload the I/O operation of this queue, according to its device type
characteristics.

Some of the virtio features can be supported according to the device
capability, for example, TSO and checksum.

Add virtio queue create, modify and query DevX commands.

7b5107bae6 common/mlx5: glue UAR allocation
The isolated, protected and independent direct access to the HW by
multiple processes is implemented via User Access Region (UAR)
mechanism.
The UAR is part of PCI address space that is mapped for direct access to
the HW from the CPU.
UAR is comprised of multiple pages, each page containing registers that
control the HW operation.
UAR mechanism is used to post execution or control requests to the HW.
It is used by the HW to enforce protection and isolation between
different processes.

Add a glue command to allocate and free an UAR.
