Perf app seem to support stateless only for now, so should mention as "supported for fixed and stateless operation only."

+dpdk-test-crypto-perf Application
+=================================
+
+The ``dpdk-test-compress-perf`` tool is a Data Plane Development Kit (DPDK)
+utility that allows measuring performance parameters of PMDs available in the
+compress tree. The application reads the data from a file (--input-file),
+dumps all the file into a buffer and fills out the data of input mbufs,
+which are passed to compress device with compression operations.
+Then, the output buffers are fed into the decompression stage, and the resulting
+data is compared against the original data (verification phase). After that,
+a number of iterations are performed, compressing first and decompressing later,
+to check the throughput rate
+(showing cycles/iteration, cycles/Byte and Gbps, for compression and decompression).
+
+
+Limitations
+~~~~~~~~~~~
+
+* Only supports the fixed compression.
+
+Command line options
+--------------------
+
+ ``--driver-name NAME``: compress driver to use
+
+ ``--input-file NAME``: file to compress and decompress
+
+ ``--extended-input-sz N``: extend file data up to this size (default: no extension)
+
+ ``--seg-sz N``: size of segment to store the data (default: 2048)
+
+ ``--burst-sz N``: compress operation burst size
+
+ ``--pool-sz N``: mempool size for compress operations/mbufs (default: 8192)
+
+ ``--max-num-sgl-segs N``: maximum number of segments for each mbuf (default: 16)
+
+ ``--num-iter N``: number of times the file will be compressed/decompressed (default: 10000)
+
+ ``--operation [comp/decomp/comp_and_decomp]``: perform test on compression, decompression or both operations
+
+ ``--huffman-enc [fixed/default]``: Huffman encoding (default: fixed)
+
+ ``--compress-level N``: compression level, which could be a single value, list or range (default: range between 1 and 9)
+
+ ``--window-sz N``: base two log value of compression window size (default: max supported by PMD)
+
+ ``-h``: prints this help
+
+
+Compiling the Application
+-------------------------
+
+**Step 1: PMD setting**
+
+The ``dpdk-test-compress-perf`` tool depends on compression device drivers PMD which
+can be disabled by default in the build configuration file ``common_base``.
+The compression device drivers PMD which should be tested can be enabled by setting::
+
+   CONFIG_RTE_LIBRTE_PMD_ISAL=y
+
+
+Running the Application
+-----------------------
+
+The tool application has a number of command line options. Here is the sample command line:
+
+.. code-block:: console
+
+   ./build/app/dpdk-test-compress-perf  -l 4 -- --driver-name compress_qat --input-file test.txt --seg-sz 8192
+    --compress-level 1:1:9 --num-iter 10 --extended-input-sz 1048576  --max-num-sgl-segs 16 --huffman-enc fixed
+
