[v3,0/8] fib: implement AVX512 vector lookup

  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

Is this series missing a 20.08 prefix in the titles?

Ah yes, forgot about it. Do you need me to resend this series with a prefix?

I will mark it as deferred for 20.08, no need to resend.
Thanks.
  

Waiting for reviews please.
