+# Intel AVF device plugin for VPP
+
+##Overview
+This plugins provides native device support for intel Adaptive Virtual
+Function (AVF). AVF is driver specification for current and future
+Intel Virtual Function devices. AVF defines communication channel between
+Physical Funciton (PF) and VF.
+In essence, today this driver can be used only with
+Intel XL710 / X710 / XXV710 adapters.
+
+##Prerequisites
+ * Driver requires newer i40e PF linux driver to be installed on the system,
+which supports virtualchnl interface. This code is tested with i40e driver
+version 2.4.6.
+
+* Driver requires MSI-X interrupt support, which is not supported by
+uio_pci_generic driver, so vfio-pci needs to be used. On systems without IOMMU
+vfio driver can still be used with recent kernels which support no-iommu mode.
+
+##Known issues
+This driver is still in experimental phase, however it shows very good
+performance numbers. Following items are not implemented (yet).
+
+* Jumbo MTU support
+* Interrupt and adaptive mode
+* NUMA support
+
+## Usage
+### System setup
+
+1. load VFIO driver
+```
+sudo modprobe vfio-pci
+```
+
+2. (systems without IOMMU only) enable unsafe NOIOMMU mode
+```
+echo Y | sudo tee /sys/module/vfio/parameters/enable_unsafe_noiommu_mode
+```
+
+3. Create and bind SR-IOV virtual function(s)
+
+Following script creates VF, assigns MAC address and binds VF to vfio-pci
+```bash
+#!/bin/bash
+
+if [ $USER != "root" ] ; then
+ echo "Restarting script with sudo..."
+ sudo $0 ${*}
+ exit
+fi
+
+setup () {
+ cd /sys/bus/pci/devices/${1}
+ driver=$(basename $(readlink driver))
+ if [ "${driver}" != "i40e" ]; then
+ echo ${1} | tee driver/unbind
+ echo ${1} | tee /sys/bus/pci/drivers/i40e/bind
+ fi
+ ifname=$(basename net/*)
+ echo 0 | tee sriov_numvfs > /dev/null
+ echo 1 | tee sriov_numvfs > /dev/null
+ ip link set dev ${ifname} vf 0 mac ${2}
+ ip link show dev ${ifname}
+ vf=$(basename $(readlink virtfn0))
+ echo ${vf} | tee virtfn0/driver/unbind
+ echo vfio-pci | tee virtfn0/driver_override
+ echo ${vf} | sudo tee /sys/bus/pci/drivers/vfio-pci/bind
+ echo | tee virtfn0/driver_override
+}
+
+# Setup one VF on PF 0000:3b:00.0 and assign MAC address
+setup 0000:3b:00.0 00:11:22:33:44:00
+# Setup one VF on PF 0000:3b:00.1 and assign MAC address
+setup 0000:3b:00.1 00:11:22:33:44:01
+```
+
+### Interface Cration
+Interfaces can be dynamically created by using following CLI:
+```
+create interface avf 0000:3b:02.0
+set int state AVF0/3b/2/0 up
+```
+
+### Interface Deletion
+Interface can be deleted with following CLI:
+```
+delete interface avf <interface name>
+```
+
+### Interface Statistics
+Interface statistics can be displayed with `sh hardware-interface <if-name>`
+command.
