* Not performance tuned.
* Snow3g(UEA2) supported only if cipher length, cipher offset fields are byte-aligned.
* Snow3g(UIA2) supported only if hash length, hash offset fields are byte-aligned.

To complete the installation - follow instructions in `Binding the available VFs to the DPDK UIO driver`_.
**Note**: If the QAT kernel modules are not loaded and you see an error like
``Failed to load MMP firmware qat_895xcc_mmp.bin`` this may be as a
result of not using a distribution, but just updating the kernel directly.
Download firmware from the kernel firmware repo at:
http://git.kernel.org/cgit/linux/kernel/git/firmware/linux-firmware.git/tree/
Copy qat binaries to /lib/firmware:
* ``cp qat_895xcc.bin /lib/firmware``
* ``cp qat_895xcc_mmp.bin /lib/firmware``
cd to your linux source root directory and start the qat kernel modules:
* ``insmod ./drivers/crypto/qat/qat_common/intel_qat.ko``
* ``insmod ./drivers/crypto/qat/qat_dh895xcc/qat_dh895xcc.ko``
**Note**:The following warning in /var/log/messages can be ignored:
``IOMMU should be enabled for SR-IOV to work correctly``
