Deepak,
The .../doc/guides/cryptodevs/qat.rst is geared toward crypto and no mention of
compression.
I am trying to figure out what it takes to have compression support on DPDK
such as new PMD driver, additional defines and/or API or chipset initialization
since the Intel QAT can support compression.
It seems to me IP payload can make good use of the hardware assisted
compression and this will be a nice feature to have.
Thanks so much,
anthony.

There is still NO compression support in DPDK which utilizes Intel(R)
QuickAssist Technology.

Have you gone through the Crypto Documentation on dpdk.org and release notes
(qat.rst) for more information?
