Subject: [PATCH] crypto: qat - fix CTX_ENABLES bits shift direction issue
Date: Wed, 16 Dec 2015 10:39:40 +0800 [thread overview]
Message-ID: <1450233580-58266-1-git-send-email-pingchao.yang@intel.com> (raw)
AE CTX bits should be 8-15 in CTX_ENABLES, so the mask
value 0xff should be left shifted 0x8.
