Subject: acl: select 256-bit AVX512 classify method by default
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=867d0d3649d8edda60c3fc863f9e491cca2c64d9;p=dpdk.git

acl: select 256-bit AVX512 classify method by default

On supported platforms, set RTE_ACL_CLASSIFY_AVX512X16 as
default ACL classify algorithm.
Note that AVX512X16 implementation uses 256-bit registers/instincts only
to avoid possibility of frequency drop.
