To use the QAT PMD an SRIOV-enabled QAT kernel driver is required. The VF
devices created and initialised by this driver will be used by the QAT PMD.

relationships between the PF/VF devices and the PMDs visible to
DPDK applications.

-Acceleration services - cryptography and compression - are provided to DPDK
-applications via PMDs which register to implement the corresponding
-cryptodev and compressdev APIs.

-Each QuickAssist VF device can expose one cryptodev PMD and/or one compressdev PMD.
+Each QuickAssist PF device exposes a number of VF devices. Each VF device can

These QAT PMDs share the same underlying device and pci-mgmt code, but are
enumerated independently on their respective APIs and appear as independent
devices to applications.
