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.
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
Vladimir Medvedkin (8):
eal: introduce zmm type for AVX 512-bit
fib: make lookup function type configurable
fib: move lookup definition into the header file
fib: introduce AVX512 lookup
fib6: make lookup function type configurable
fib6: move lookup definition into the header file
fib6: introduce AVX512 lookup
app/testfib: add support for different lookup functions
