ADQ Configuration on SR-IOV Virtual Functions
Single Root I/O Virtualization (SR-IOV) is a specification that allows a single physical PCIe device to present multiple separate PCIe devices in a virtual environment. The Intel® Ethernet Adaptive Virtual Function (Intel® Ethernet AVF) iavf driver for Linux can be configured with ADQ on Intel® Ethernet 800 Series Network Adapters to provide ADQ performance enhancements in a virtual environment. In this section, the iavf driver is referred to as VF for Virtual Function, and the ice driver is referred to as PF for Physical Function.
The following variables are used in the examples in this section:
| $vfdriverver | The iavf driver version. |
| $numvfs | The number of VFs to spawn on the SUT. |
| $iface_pf | The Physical Function (PF) interface name on the SUT. |
| $iface_vf | The Virtual Function (VF) interface name on the SUT. |
| $ipaddr_pf | The IP Address assigned to the PF interface on the SUT. |
| $ipaddr_vf | The IP Address assigned to the VF interface on the SUT. |
| $ipaddrclient | The IP Address assigned to the PF interface on the client where application is being run. |
| $app_port | The TCP port on the SUT where the application is being run. |
