Subject: [Patch v2 3/7] crypto: qce: Add mode for rfc4309
Date: Sat, 17 Apr 2021 09:24:59 -0400 [thread overview]
Message-ID: <20210417132503.1401128-4-thara.gopinath@linaro.org> (raw)
In-Reply-To: <20210417132503.1401128-1-thara.gopinath@linaro.org>
rf4309 is the specification that uses aes ccm algorithms with IPsec
security packets. Add a submode to identify rfc4309 ccm(aes) algorithm
in the crypto driver.
Signed-off-by: Thara Gopinath <thara.gopinath@linaro.org>

v1->v2:
- Moved up the QCE_ENCRYPT AND QCE_DECRYPT bit positions so that
addition of other algorithms in future will not affect these
macros.
