Subject: build: fix default arm64 instruction level
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=e6084f36256668d60addff8f3023c89d8154b031;p=dpdk.git

build: fix default arm64 instruction level

The make based build system has crc+crypto instruction
support for the default arm64 build.
http://dpdk.org/browse/dpdk/tree/mk/machine/armv8a/rte.vars.mk#n31

This patch fixes the disparity with meson build flags for armv8.
As a bonus, This patch fixes the following errors with
ip_pipeline example application.

Assembler messages:
Error: selected processor does not support `crc32cx w3,w3,x0'

Fixes: c6e536e38437 ("build: add more implementers IDs and PNs for ARM")
