+=======================================================
+Improve ixgbe_get_vf_queue to include extra information
+=======================================================
+
+Prerequisites
+=============
+
+1. Hardware:
+   Ixgbe
+   connect tester to pf with cable.
+
+2. software:
+   dpdk: http://dpdk.org/git/dpdk
+   scapy: http://www.secdev.org/projects/scapy/
+
+3. bind the pf to dpdk driver::
+
+    ./usertools/dpdk-devbind.py -b igb_uio 05:00.0
+
+   the mac address of 05:00.0 is 00:00:00:00:01:00
+
+4. create 1 vf from pf::
+
+    echo 1 >/sys/bus/pci/devices/0000:05:00.0/max_vfs
+
+5. Detach VF from the host, bind them to pci-stub driver::
+
+    modprobe pci-stub
+    echo "8086 10fb" > /sys/bus/pci/drivers/pci-stub/new_id
+    echo "0000:05:10.0" > /sys/bus/pci/drivers/ixgbevf/unbind
+    echo "0000:05:10.0" > /sys/bus/pci/drivers/pci-stub/bind
+
+6. Lauch the VM with the VF PCI passthrough::
+
+    taskset -c 2-5 qemu-system-x86_64 \
+    -enable-kvm -m 8192 -smp cores=4,sockets=1 -cpu host -name dpdk1-vm1 \
+    -drive file=/home/VM/centOS7_1.img \
+    -device pci-assign,host=05:10.0 \
+    -netdev tap,id=ipvm1,ifname=tap3,script=/etc/qemu-ifup -device rtl8139,netdev=ipvm1,id=net0,mac=00:00:00:00:00:01 \
+    -localtime -vnc :2 -daemonize
+
+7. login VM, get VF's mac adress is 2e:ae:7f:16:6f:e7
+
+Test case 1: DPDK PF, kernel VF, enable DCB mode with TC=4
+==========================================================
+
+1. start the testpmd on PF::
+
+    ./x86_64-native-linuxapp-gcc/app/testpmd -c 1ffff -n 4 -- -i --rxq=4 --txq=4 --nb-cores=16    
+    testpmd> port stop 0
+    testpmd> port config 0 dcb vt on 4 pfc off
+    testpmd> port start 0
+
+2. check if VF port is linked. if vf port is down, reload the ixgbevf driver::
+
+    rmmod ixgbevf
+    modprobe ixgbevf
+
+   then you can see VF information in PF side::
+
+    PMD: VF 0: enabling multicast promiscuous
+    PMD: VF 0: disabling multicast promiscuous
+
+3. check VF's queue number::
+
+    ethtool -S ens3
+
+   there is 1 tx queue and 4 rx queues which equals TC number.
+
+4. send packet from tester to VF::
+
+    pkt1 = Ether(dst="2e:ae:7f:16:6f:e7", src="00:02:00:00:00:01")/Dot1Q(prio=0, vlan=0)/IP()/Raw('x'*20)
+    pkt2 = Ether(dst="2e:ae:7f:16:6f:e7", src="00:02:00:00:00:01")/Dot1Q(prio=1, vlan=0)/IP()/Raw('x'*20)
+    pkt3 = Ether(dst="2e:ae:7f:16:6f:e7", src="00:02:00:00:00:01")/Dot1Q(prio=2, vlan=0)/IP()/Raw('x'*20)
+    pkt4 = Ether(dst="2e:ae:7f:16:6f:e7", src="00:02:00:00:00:01")/Dot1Q(prio=3, vlan=0)/IP()/Raw('x'*20)
+    pkt5 = Ether(dst="2e:ae:7f:16:6f:e7", src="00:02:00:00:00:01")/Dot1Q(prio=4, vlan=0)/IP()/Raw('x'*20)
+    pkt6 = Ether(dst="2e:ae:7f:16:6f:e7", src="00:02:00:00:00:01")/Dot1Q(prio=5, vlan=0)/IP()/Raw('x'*20)
+    pkt7 = Ether(dst="2e:ae:7f:16:6f:e7", src="00:02:00:00:00:01")/Dot1Q(prio=6, vlan=0)/IP()/Raw('x'*20)
+    pkt8 = Ether(dst="2e:ae:7f:16:6f:e7", src="00:02:00:00:00:01")/Dot1Q(prio=7, vlan=0)/IP()/Raw('x'*20)
+    pkt9 = Ether(dst="2e:ae:7f:16:6f:e7", src="00:02:00:00:00:01")/Dot1Q(prio=0, vlan=1)/IP()/Raw('x'*20)
+    pkt10 = Ether(dst="2e:ae:7f:16:6f:e7", src="00:02:00:00:00:01")/IP()/Raw('x'*20)
+
+5. check the packets with different User Priority mapping to TC::
+
+    ethtool -S ens3
+
+   check the NIC statistics to check the packets increasing of different rx queue.
+   pkt1 to queue 0, pkt2 to queue 1, pkt3 to queue 2, pkt4 to queue 3,
+   pkt5-pkt8 to queue 0, VF can't get pkt9, pkt10 to queue 0.
+
+Test case 2: DPDK PF, kernel VF, disable DCB mode
+=================================================
+
+1. start the testpmd on PF::
+
+    ./x86_64-native-linuxapp-gcc/app/testpmd -c 1ffff -n 4 -- -i --nb-cores=16
+
+2. check if VF port is linked. if vf port is down, reload the ixgbevf driver::
+
+    rmmod ixgbevf
+    modprobe ixgbevf
+
+   then you can see VF information in PF side::
+
+    PMD: VF 0: enabling multicast promiscuous
+    PMD: VF 0: disabling multicast promiscuous
+
+3. set vlan insert to vf::
+
+    set vf vlan insert 0 0 1
+
+4. check VF's queue number::
+
+    ethtool -S ens3
+
+   there is 2 tx queues and 2 rx queues as default number.
+
+4. send packet from tester to VF::
+
+    pkt1 = Ether(dst="2e:ae:7f:16:6f:e7", src="00:02:00:00:00:01")/IP()/Raw('x'*20)
+    pkt2 = Ether(dst="2e:ae:7f:16:6f:e7", src="00:02:00:00:00:01")/IP(src="192.168.0.1", dst="192.168.0.3")/UDP(sport=23,dport=24)/Raw('x'*20)
+
+5. check the NIC statistics to verify the different packets mapping to
+   different queues according RSS rule::
+
+    ethtool -S ens3
+
+   send 100 pkt1 to VF, all the packets received by queue 0,
+   then, send 100 pkt2 to VF, all the packets received by queue 1.
