Does QAT communication chipest 8950 support stateful Deflate Compression?

Hi,
Now I am trying to run the stateful data compression sample located in /dc/stateful_sample .My QAT is COMMUNICATION CHIPSET 8950. However,I found that this function is not supported by QAT. When i want to run this sample,the debug output is as following:
__________________________________________________________________________
[root@node5 stateful_sample]# ./dc_stateful_sample
main(): Starting Stateful Compression Sample Code App ...
dcStatefulSample(): cpaDcQueryCapabilities
dcStatefulSample(): Error: Unsupported functionality compression
main():
Stateful Compression Sample Code App failed
__________________________________________________________________________
Then i found the definition of the compression capabilities in sal_compression.c :
__________________________________________________________________________
#ifdef CNV_STRICT_MODE
pInstanceCapabilities->statefulDeflateCompression = CPA_FALSE;
#else
pInstanceCapabilities->statefulDeflateCompression = CPA_TRUE;
_________________________________________________________________________
I did not find the definition of CNV_STRICT_MODE，so is my QAT really not support stateful deflate compression?

Regards.
