From: Ravi Kumar Date: Mon, 19 Mar 2018 12:23:38 +0000 (-0400) Subject: crypto/ccp: support session related ops X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=29610e41c1a91db9ce5308931ff3cb8d58e491c8;p=dpdk.git crypto/ccp: support session related ops Added crypto session specific basic crypto ops callback functions. Added different crypto engine types and definitions.
