[dpdk-dev] [PATCH v2 0/6] fib: implement AVX512 vector lookup

[Vladimir Medvedkin]

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.

v2:
 - rename rte_zmm to __rte_x86_zmm to reflect its internal usage
 - make runtime decision to use avx512 lookup

Vladimir Medvedkin (6):
  eal: introduce zmm type for AVX 512-bit
  fib: make lookup function type configurable
  fib: introduce AVX512 lookup
  fib6: make lookup function type configurable
  fib6: introduce AVX512 lookup
  app/testfib: add support for different lookup functions
