eal/arm64: add 128-bit atomic compare exchange

This patch adds the implementation of the 128-bit atomic compare
exchange API on aarch64. Using 64-bit 'ldxp/stxp' instructions
can perform this operation. Moreover, on the LSE atomic extension
accelerated platforms, it is implemented by 'casp' instructions for
better performance.

Since the '__ARM_FEATURE_ATOMICS' flag only supports GCC-9, this
patch adds a new config flag 'RTE_ARM_FEATURE_ATOMICS' to enable
the 'cas' version on older version compilers.
For octeontx2, we make sure that the lse (and other) extensions are
enabled even if the compiler does not know of the octeontx2 target
cpu.

Since direct x0 register used in the code and cas_op_name() and
rte_atomic128_cmp_exchange() is inline function, based on parent
function load, it may corrupt x0 register aka break aarch64 ABI.
Define CAS operations as rte_noinline functions to avoid an ABI
break [1].

service: avoid false sharing on core state

For a valid service, the core mask of the service
is checked against the current core and the corresponding
entry in the active_on_lcore array is set or reset.

Upto 8 cores share the same cache line for their

Some number of these entries also share the cache line with

hence this false sharing also makes the service_valid() check

This code was added 7+ years ago in

presumably when variant TSCs were still somewhat common.

But this code doesn't do anything except print a warning,

  [...] -lrte_telemetry [...] -Wl,--no-as-needed [...]
Which means telemetry no more benefits from --no-as-needed anyway.

Overlinking problems get triggered by the meson generated pkgconfig which
will have:
   [...] -Wl,--no-as-needed <somelibsusedbydpdk>
This will overlink <somelibs> and in addition anything that follows
as it also doesn't wrap back to --as-needed. So if a projects includes
dpdk libs + <other> it will also consider <other> with --no-as-needed.

net/mlx5: adjust inline setting for large Tx queue sizes

The hardware may have limitations on maximal amount of
supported Tx descriptors building blocks (WQEBB). Application
requires the Tx queue must accept the specified amount of packets.
If inline data feature is engaged the packet may require more WQEBBs
and overall amount of blocks may exceed the hardware capabilities.
Application has to make a trade-off between Tx queue size and maximal
data inline size.

In case if the inline settings are not requested explicitly with
devarg keys the default values are used. This patch adjusts the
applied default values if large Tx queue size is requested and
default inline settings can not be satisfied due to hardware
limitations.

The explicitly requested inline setting may be aligned (enlarging
only) by configurations routines to provide better WQEBB filling,
this implicit alignment is the subject for adjustment either.

net/cxgbe: fix races on flow API operations

When rules are being inserted from multiple cores, there are several
race conditions during rte_flow operations.

For example, when inserting rules from 2 cores simultaneously, both
the cores try to fetch a free available filter entry and they both
end up fetching the same entry. Both of them start overwriting the

net/bnxt: support RSS action

Add support for RSS action during flow creation.

group id should not be 0 when RSS action is specified. Driver will
return an error for such a flow.

If a group id is used to create a filter with “n” RSS queues, it cannot
be used to create a filter with a different number of RSS queues till
all the flows using that combination are deleted.

While creating a flow if a group id groups a certain Rx queue ids for
RSS, the same group id shall not create a flow with a different group of
Rx queue ids till all the flows belonging to the group ids are deleted.

net/szedata2: fix dependency check

The library libsze2 provides a pkg-config file: libsze2.pc.
Looking for this .pc file - with dependency() - is preferred
than looking for the library - with cc.find_library().

If the library is not installed in a standard path,
it can be found thanks to PKG_CONFIG_PATH variable.
The previous solution required to use CFLAGS and LDFLAGS
environment variables.
