e8146c63c3 net/mlx5: support represented port item in flow rules
Add support for represented_port item in pattern. And if the spec and mask
both are NULL, translate function will not add source vport to matcher.

For example, testpmd starts with PF, VF-rep0 and VF-rep1, below command
will redirect packets from VF0 and VF1 to wire:
testpmd> flow create 0 ingress transfer group 0 pattern eth /
represented_port / end actions represented_port ethdev_id is 0 / end

42fbb8e85d eal/linux: allocate worker lcore stacks in hugepages
Add support for using hugepages for worker lcore stack memory. The
intent is to improve performance by reducing stack memory related TLB
misses and also by using memory local to the NUMA node of each lcore.

EAL option '--huge-worker-stack[=stack-size-in-kbytes]' is added to allow
the feature to be enabled at runtime. If the size is not specified,
the system pthread stack size will be used.

e1522b328c ip_frag: fix build with GCC 12

4200c4d625 net/qede: fix build with GCC 12
The x86 version of rte_memcpy can cause warnings. The driver does
not need to use rte_memcpy for everything. Standard memcpy is
just as fast and safer; the compiler and static analysis tools
treat memcpy specially.

38e9762be1 net/i40e: add outer VLAN processing
Outer VLAN processing is supported after firmware v8.4, kernel driver
also change the default behavior to support this feature. To align with
kernel driver, add support for outer VLAN processing in DPDK.

But it is forbidden for firmware to change the Inner/Outer VLAN
configuration while there are MAC/VLAN filters in the switch table.
Therefore, we need to clear the MAC table before setting config,
and then restore the MAC table after setting.

This will not impact on an old firmware.

Parameters:
    <port_id>       the PF Port ID
    <config_path>   dumped runtime configure file, if not a absolute path,
                    it will be dumped to testpmd running directory.

For example:

unused PF port of the NIC first, and then dump the PF's runtime configure
as target output.

3d171da6e7 common/cnxk: add include for macro definition
The header file "roc_io.h" uses the "__plt_always_inline" macro but
don't include "roc_platform.h" to get the definition of it. This
inclusion is not necessary for compilation, but the lack of it can
confuse some indexers - such as those in eclipse, which reports the
lines:

"static __plt_always_inline uint64_t"

as possible definitions of a variable called "uint64_t". This confusion
leads to uint64_t being flagged as an unknown type in all other parts of
the project being indexed, e.g. across all of DPDK code.

Adding in the include of roc_platform.h makes it clear to the indexer
that those lines are  part of a function definition, and that allows
eclipse to correctly recognise uint64_t as a type from stdint.h

0efcd352e2 eal/unix: make stack dump signal safe
rte_dump_stack() needs to be usable in situations when a bug is
encountered and from signal handlers (such as SEGV).

Glibc backtrace_symbols() calls malloc which makes it
dangerous in a signal handler that is handling errors that maybe
due to memory corruption. Additionally, rte_log() is unsafe because
syslog() is not signal safe; printf() is also documented as
not being safe.

This version formats message and uses writev for each line in a manner
similar to what glibc version of backtrace_symbols_fd() does. The
FreeBSD version of backtrace_symbols_fd() is not signal safe.

Sample output:

0: ./build/app/dpdk-testpmd (rte_dump_stack+0x2b) [560a6e9c002b]
1: ./build/app/dpdk-testpmd (main+0xad) [560a6decd5ad]
2: /lib/x86_64-linux-gnu/libc.so.6 (__libc_start_main+0xcd) [7fd43d3e27fd]
3: ./build/app/dpdk-testpmd (_start+0x2a) [560a6e83628a]

2fbada9154 vhost/crypto: fix descriptor processing
copy_data was returning a pointer to an increased (off by one) descriptor.
Subsequent calls to copy_data in the library were then failing.
Fix this by incrementing the descriptor only if there is some left data
to copy.
