Subject[Patch v4 3/7] crypto: qce: Add mode for rfc4309
Date
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.

Reviewed-by: Bjorn Andersson <bjorn.andersson@linaro.org>
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.
