+VFD as SRIOV Policy Manager
+============================
+
+VFD is SRIOV Policy Manager (daemon) running on the host allowing 
+configuration not supported by kernel NIC driver, supports ixgbe and 
+i40e NIC. Run on the host for policy decisions w.r.t. what a VF can and 
+cannot do to the PF. Only the DPDK PF would provide a callback to implement 
+these features, the normal kernel drivers would not have the callback so 
+would not support the features. Allow passing information to application 
+controlling PF when VF message box event received such as those listed below, 
+so action could be taken based on host policy. Stop VM1 from asking for 
+something that compromises VM2. Use DPDK DPDK PF + kernel VF mode to verify 
+below features. 
+
+Case 1: Set up environment and load driver
+============================================
+1. Get the pci device id of DUT, load ixgbe driver to required version, 
+   take Niantic for example::
+        rmmod ixgbe
+        insmod ixgbe.ko
+
+2. Host PF in DPDK driver. Create VFs from PF with dpdk driver::
+	./tools/dpdk-devbind.py -b igb_uio 05:00.0
+	echo 2 >/sys/bus/pci/devices/0000\:05\:00.0/max_vfs 
+	
+3. Check ixgbevf version and update ixgbevf to required version::
+	
+4. Detach VFs from the host::
+	rmmod ixgbevf
+
+5. Pass through VF 05:10.0 and 05:10.2 to VM0,start and login VM0
+
+6. Check ixgbevf version in VM and update to required version
+
+
+Case 2 : Link
+==========================================
+Pre-environment::
+  (1)Host one DPDK PF and create two VFs, pass through VF0 and VF1 to VM0, 
+     start VM0

+
+Steps:  
+
+1. Enable multi-queues to start DPDK PF::
+        ./testpmd -c f -n 4 -- -i --rxq=4 --txq=4
+
+2. Link up kernel VF and expect VF link up
+
+3. Link down kernel VF and expect VF link down
+
+4. Repeat above 2~3 for 100 times, expect no crash or core dump issues.

+
+Steps: 
+
+1. Ifconfig IP on VF0 and VF1
+
+2. Ifconfig IP on link partner PF, name as tester PF
+
+3. Start inbound and outbound pings, check ping successfully.
+
+4. Link down the devx, stop the pings, link up the devx then restart the 
+   pings, check port could ping successfully. 
+
+5. Repeat step 3~4 for 5 times
+   
+
+Test Case 4: reset
+==========================================
+Pre-environment::
+  (1)Establish link with link partner.
+  (2)Host one DPDK PF and create two VFs, pass through VF0 to VM0 and VF1 to 
+     VM1, start VM0 and VM1
+  (3)Load host DPDK driver and VM kernel driver
+
+Steps: 
+
+1. Check host testpmd and PF at link up status
+
+2. Link up VF0 in VM0 and VF1 in VM1 
+
+3. Link down VF1 in VM1 and check no impact on VF0 status
+

+
+5. Use tcpdump to dump packet on VF0
+
+6. Send packets to VF0 using IXIA or scapy tool, expect RX successfully
+
+7. Link down and up DPDK PF, ensure that the VF recovers and continues to 
+   receive packet. 
+
+8. Load VF1 kernel driver and expect no impact on VF0

+        ifconfig ens3 add efdd::9fc8:6a6d:c232:f1c0
+
+5. Delete IPv6 on kernel VF::
+        ifconfig ens3 del efdd::9fc8:6a6d:c232:f1c0
+
+6. Modify MAC address on kernel VF::
+        ifconfig ens3 hw ether 00:AA:BB:CC:dd:EE
+
+7. Send packet to modified MAC, expect VF can receive packet successfully
+
+
+Test Case 6: add/delete vlan
+==========================================
+Pre-environment::
+  (1)Establish link with link partner.
+  (2)Host one DPDK PF and create one VF, pass through VF0 to VM0, start VM0 
+  (3)Load host DPDK driver and VM0 kernel driver
+
+Steps: 
+
+1. Add random vlan id(0~4095) on kernel VF0(e.g: ens3), take vlan id 51 
+   for example::
+        modprobe 8021q
+        vconfig add ens3 51
+
+2. Check add vlan id successfully, expect to have ens3.51 device::
+        ls /proc/net/vlan 
+
+3. Send packet from tester to VF MAC with not-matching vlan id, check the 
+   packet can't be received at the vlan device
+
+4. Send packet from tester to VF MAC with matching vlan id, check the 
+   packet can be received at the vlan device.
+
+5. Delete configured vlan device::
+        vconfig rem ens3.51
+
+6. Check delete vlan id 51 successfully
+
+7. Send packet from tester to VF MAC with vlan id(51), check that the 
+   packet can’t be received at the VF. 
+
+
+Test Case 7: Get packet statistic
+==========================================
+Pre-environment::
+  (1)Establish link with link partner.
+  (2)Host one DPDK PF and create one VF, pass through VF0 to VM0, start VM0 
+  (3)Load host DPDK driver and VM0 kernel driver
+
+Steps: 
+
+1. Send packet to kernel VF0 mac
+

+        ethtool -S ens3
+
+
+Test Case 8: MTU

+Pre-environment::
+  (1)Establish link with link partner.
+  (2)Host one DPDK PF and create one VF, pass through VF0 to VM0, start VM0 
+  (3)Load host DPDK driver and VM0 kernel driver
+
+Steps: 
+
+1. Check DPDK PF and kernel VF mtu, normal as 1500
+
+2. Use scapy to send one packet with length as 2000 with DPDK PF MAC as 
+   DST MAC, check that DPDK PF can't receive packet
+
+3. Use scapy to send one packet with length as 2000 with kernel VF MAC as 
+   DST MAC, check that Kernel VF can't receive packet
+
+4. Change DPDK PF mtu as 3000,check no confusion/crash on kernel VF::
+        Testpmd > port stop all
+        Testpmd > port config mtu 0 3000
+        Testpmd > port start all
+
+5. Use scapy to send one packet with length as 2000 with DPDK PF MAC as 
+   DST MAC, check that DPDK PF can receive packet
+
+6. Change kernel VF mtu as 3000, check no confusion/crash on DPDK PF::
+        ifconfig eth0 mtu 3000
+
+7. Use scapy to send one packet with length as 2000 with kernel VF MAC 
+   as DST MAC, check Kernel VF can receive packet
+
+Note:
+HW limitation on 82599, need add “--max-pkt-len=<length>” on testpmd to 
+set mtu value, all the VFs and PF share same MTU, the largest one takes 
+effect.

+
+3. Send packet from tester with random DST MAC, check the packet can be 
+   received by DPDK PF and kernel VF
+
+4. Disable DPDK PF promisc mode
+
+5. Set up kernel VF tcpdump with -p parameter, which means disable promisc 
+   mode::
