adding virtual ethernet\n+ports providing a logical representation in DPDK for SR-IOV virtual function\n+(VF) devices for control and monitoring.\n+\n+These port representor ethdev instances can be spawned on an as needed basis\n+through configuration parameters passed to the driver of the underlying\n+base device using devargs ``-a pci:dbdf,representor=[0]``\n+\n+.. note::\n+\n+ Base device is the PF whose VFs will be represented by these representors\n+\n+ Above devarg parameters can be provided as a range of representor device\n+ ``-a pci:dbdf,representor=[0-3]`` or a single representor device on need\n+ basis ``-a pci:dbdf,representor=[0]``\n+\n+In case of exception path (i.e. until the flow definition is offloaded to the\n+hardware), packets transmitted by the VFs shall be received by these\n+representor port, while packets transmitted by representor ports shall be\n+received by respective VFs.\n+\n+On receiving the VF traffic via these representor ports, applications holding\n+these representor ports can decide to offload the traffic flow into the HW.\n+Henceforth the matching traffic shall be directly steered to the respective\n+VFs without being received by the application.\n+\n+Current virtual representor port PMD supports following operations:\n+\n+- Get and clear VF statistics\n+- Set mac address\n+- Flow operations - create, validate, destroy, query,
