This patch series implements vectorized lookup using AVX512 for
ipv4 dir24_8 and ipv6 trie algorithms.
Also introduced rte_fib_set_lookup_fn() to change lookup function type.
Added option to select lookup function type in testfib application.
Depends-on: patch-81125 ("eal: add max SIMD bitwidth")
v12:
- rebase on the latest main
- drop "eal/x86: introduce AVX 512-bit type" patch
v11:
- fix compillation issue with unused nh_sz variable
v10:
- reflects the latest changes in the "eal: add max SIMD bitwidth" patch
- add en extra doxygen comments
- rebuild on the latest main
v9:
- meson reworked
- integration with max SIMD bitwidth patchseries
- changed the logic of function selection on init
v8:
- remove Makefile related changes
- fix missing doxygen for lookup_type
- add release notes
v7:
- fix RTE_X86_ZMM_MASK macro
v6:
- style fixes
v5:
- prefix zmm macro in rte_vect.h with RTE_X86
- remove unnecessary typedef for _x86_zmm_t
- reword commit title
- fix typos
v4:
- use __rte_aligned() instead of using compiler attribute directly
- rework and add comments to meson.build
v3:
- separate out the AVX-512 code into a separate file
v2:
- rename rte_zmm to __rte_x86_zmm to reflect its internal usage
- make runtime decision to use avx512 lookup
