Subject: [PATCH 1/7] crypto: qce: common: Add MAC failed error checking
Date: Thu, 25 Feb 2021 13:27:10 -0500 [thread overview]
Message-ID: <20210225182716.1402449-2-thara.gopinath@linaro.org> (raw)
In-Reply-To: <20210225182716.1402449-1-thara.gopinath@linaro.org>
MAC_FAILED gets set in the status register if authenthication fails
for ccm algorithms(during decryption). Add support to catch and flag
this error.
