Hi Fan,
There is an ARM64 port for IPSEC-MB
https://gitlab.arm.com/arm-reference-solutions/ipsec-mb .
When we compile DPDK with this IPSEC-MB port for ARM64, the vector_mode value
doesn't matter.
And the cpuflag #defines RTE_CPUFLAG_AVX512F, RTE_CPUFLAG_AVX2 etc. are not
available in ARM64. So these need to be made x86 specific.
Thank you
Ashwin
