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.
