From a3f2185a29df084611641e964aa93d1a6ee2212c Mon Sep 17 00:00:00 2001 From: Herbert Xu Date: Wed, 27 May 2015 16:03:51 +0800 Subject: [PATCH] crypto: tcrypt - Switch to new AEAD interface This patch makes use of the new AEAD interface which uses a single SG list instead of separate lists for the AD and plain text.
