The AltiVec header file is defining "vector", except in C++ build.
The keyword "vector" may conflict easily.
As a rule, it is better to use the alternative keyword "__vector".
The DPDK header file rte_altivec.h takes care of undefining "vector",
so the applications and dependencies are free to define the name "vector".
This is a compatibility breakage for applications which were using
the keyword "vector" for its AltiVec meaning.

Previously, on lookup hit, the hit key had its timer automatically
rearmed with the same timeout in order to prevent its expiration. Now,
a broader set of actions is available on lookup hit, which has to be
managed explicitly: the key can have its timer rearmed with the same
or with a different timeout, or the key timer can be left unmodified.
The latter option allows the key to expire naturally when the timer
eventually runs out, unless the key is hit again and its timer rearmed
at that point. Needed by the TCP connection tracking state machine.

Add support for packet recirculation. The current packet is flagged
for recirculation using the new "recirculate" instruction; on TX, this
flag causes the packet to execute the full pipeline again as if it was
a new packet, except the packet meta-data is preserved. The new
"recircid" instruction can be used to read the pass number in case the
packet goes several times through the pipeline.

The packet mirroring is configured through slots and sessions, with

The new "mirror" instruction assigns one of the existing sessions to a

transmitted or dropped.

To control desired behavior '--ipv6' command-line option is extended

To be more precise:
'--ipv6' - use 4x4B fields format (default behavior)
'--ipv6=4B' - use 4x4B fields format (default behavior)

Forcing inlining in test_ring_enqueue and test_ring_dequeue can cause
the compiled code to grow extensively when compiled with no optimization
(-O0 or -Og). This is default in the meson's debug configuration. This
can collide with compiler bugs and cause issues during linking of unit
tests where the api_type or esize are non-const variables causing
inlining cascade. In perf tests this is not the case in perf-tests as
esize and api_type are const values.
One such case was discovered when porting DPDK to RISC-V. GCC 11.2 (and
no fix still in 12.1) is generating a short relative jump instruction
(J <offset>) for goto and for loops. When loop body grows extensively in
ring test, the target offset goes beyond supported offfset of +/- 1MB
from PC. This is an obvious bug in the GCC as RISC-V has a
two-instruction construct to jump to any absolute address (AUIPC+JALR).
However there is no reason to force inlining as the test code works
perfectly fine without it.
GCC has a bug report for a similar case (with conditionals):
