So the dpdk-qat sample application is a sample of how to use the QAT 
library APIs from a DPDK application allowing the user to schedule work 
with the QAT kernel devices. The QAT API has support for a number of QAT 
devices (both the cave-creek and coleto-creek family of devices) which 
support symmetric crypto, asymmetric crypto and compression operations.

The l2fwd application demonstrates using the new DPDK symmetric crypto 
APIs in packet processing work flow, with the crypto processing 
implemented by DPDK userspace PMDs, this currently includes support for 
both the AES-NI multi-buffer PMD as well as the QAT PMD.
