Our use case was unique. We are testing application running in QEMU on Windows and the test driver is a Windows application. The Windows application interacts with DPDK inside QEMU over UDP. For example, test driver builds a packet and sends it to the DPDK appliance and expects a given result: rewrite, drop, etc.
