Subject: common/cnxk: add AE definitions for asymmetric crypto
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=1132ad0f08a5671e73258daf544e6c26bb9ff45a;p=dpdk.git

common/cnxk: add AE definitions for asymmetric crypto

Microcode AE opcodes support asymmetric operations. Add defines
and structs defined by microcode.
