From 298c926c6d7f50d91d6acb76c33b83bab5b5bd5c Mon Sep 17 00:00:00 2001 From: Adrian Hoban Date: Mon, 20 Sep 2010 16:05:12 +0800 Subject: crypto: cryptd - Adding the AEAD interface type support to cryptd This patch adds AEAD support into the cryptd framework. Having AEAD support in cryptd enables crypto drivers that use the AEAD interface type (such as the patch for AEAD based RFC4106 AES-GCM implementation using Intel New Instructions) to leverage cryptd for asynchronous processing.
