Supported AEAD algorithms:
* ``RTE_CRYPTO_AEAD_AES_GCM``
* ``RTE_CRYPTO_AEAD_AES_CCM``
Installation
------------
Information about kernel, rootfs and toolchain can be found at
@ -49,3 +90,9 @@ For example, below commands can be run to get hold of a device node by VFIO.
io_device_name="vfio-platform"
echo $io_device_name > /sys/bus/platform/devices/${SETUP_SYSFS_DEV_NAME}/driver_override
echo ${SETUP_SYSFS_DEV_NAME} > /sys/bus/platform/drivers_probe
Limitations
-----------
* Only supports the session-oriented API implementation (session-less APIs are not supported).
* CCM is not supported on Broadcom`s SoCs having FlexSparc4 unit.
