Subject: [dpdk-dev] [PATCH 1/3] crypto/aesni_gcm: move pre-counter block to GCM driver
Date: Thu, 25 Aug 2016 13:02:41 +0100 [thread overview]
Message-ID: <1472126563-31268-2-git-send-email-arkadiuszx.kusztal@intel.com> (raw)
In-Reply-To: <1472126563-31268-1-git-send-email-arkadiuszx.kusztal@intel.com>
This patch moves computing of pre-counter block into the AESNI-GCM
driver so it can be moved from test files.
