+Kernel PF + VF test plan
+========================
+
+Intel Adaptive Virtual Function is aimed to provide a common VF for VM
+which means just need one unified VF driver so you don't have to reload
+different VF driver when you upgrade the PF NIC.
+One of the advantages is you don't have to do any modification for code or
+hardware for an existing VM image running on the new NIC.
+
+Requirement
+===========
+This plan for VF only supports kernel PF scenario.
+
+Hardware
+========
+ICE/I40E driver NIC.
+
+Prerequisites
+=============
+1. Get the pci device id of DUT, for example::
+
+ ./usertools/dpdk-devbind.py -s
+
+ 0000:18:00.0 'Device 1592' if=enp24s0f0 drv=ice unused=igb_uio
+ 0000:18:00.1 'Device 1592' if=enp24s0f1 drv=ice unused=igb_uio
+
+2. Create 2 VF from 2 kernel PF::
+
+ echo 1 > /sys/bus/pci/devices/0000\:18\:00.0/sriov_numvfs
+ echo 1 > /sys/bus/pci/devices/0000\:18\:00.1/sriov_numvfs
+
+3. Set VF mac as 00:01:23:45:67:89::
+
+ ip link set $PF_INTF vf 0 mac 00:01:23:45:67:89
+
+4. Test IAVF cases on host or in qemu
+
+5. Bind VF device to vfio-pci::
+
+ usertools/dpdk-devbind.py --force --bind=vfio-pci 0000:18:01.0 0000:18:09.0
+
+launch testpmd::
+
+ ./<build_target>/app/dpdk-testpmd -c f -n 4 -- -i
+
+.. note::
+
+ 1.the kernel driver has MAC and VLAN Anti-Spoofing feature for VFs, the default is enable.
+ disabled for vfs: ip link set <ethX> vf <vf id> spoofchk {off|on}
+
+ 2.for vf-vlan-pruning in ethtool --set-priv-flag, enable function to receive specific vlan packet.
