* SNOW 3G (UIA2) and ZUC (EIA3) supported only if hash length and offset fields are byte-multiple.
* No BSD support as BSD QAT kernel driver not available.
* ZUC EEA3/EIA3 is not supported by dh895xcc devices
-* Maximum additional authenticated data (AAD) for GCM is 240 bytes long.
+* Maximum additional authenticated data (AAD) for GCM is 240 bytes long and must be passed to the device in a buffer rounded up to the nearest block-size multiple (x16) and padded with zeros.
* Queue pairs are not thread-safe (that is, within a single queue pair, RX and TX from different lcores is not supported).

Build Configuration
~~~~~~~~~~~~~~~~~~~
QAT compression PMD needs intermediate buffers to support Deflate compression
with Dynamic Huffman encoding. CONFIG_RTE_PMD_QAT_COMP_IM_BUFFER_SIZE
specifies the size of a single buffer, the PMD will allocate a multiple of these,
-plus some extra space for associated meta-data. For GEN2 devices, 20 buffers plus
-1472 bytes are allocated.
+plus some extra space for associated meta-data. For GEN2 devices, 20 buffers are
+allocated while for GEN1 devices, 12 buffers are allocated, plus 1472 bytes overhead.
.. Note::
QAT crypto PMD can be tested by running the test application::
make defconfig
- make test-build -j
+ make -j
cd ./build/app
./test -l1 -n1 -w <your qat bdf>
RTE>>cryptodev_qat_autotest

sed -i 's,\(CONFIG_RTE_COMPRESSDEV_TEST\)=n,\1=y,' build/.config
