One comment about the test plan, can we verify if  recevice_pkts == send_pkts ?

Best Regards
Yulong Pei

+VF to VF Bridge testplan
+========================
+This test suite aims to validate the bridge function on physical 
+functional for virtual functional to virtual functional communication.
+Cases of the suite based on the vm to vm test scenario, echo vm needs 
+on vf, and both of the vfs generated from the same pf port.
+
+Prerequisites: 
+==============
+
+On host:
+
+        Hugepages: at least 10 G hugepages, 6G(for vm on which run 
+ pktgen as stream source end) + 2G(for vm on which run testpmd as 
+ receive end) + 2G(for host used)
+
+        Guset: two img with os for kvm qemu
+
+        NIC: one pf port
+
+        pktgen-dpdk: need a pktgen-dpdk tarball under $DTS/dep/, as 
+ it's named: pktgen-dpdk.tar.gz
+
+On Guest:
+
+        Stream Source end: scapy pcpay and essential tarballs for 
+ compile pktgen-dpdk tools
+
+
+Set up basic virtual scenario:
+==============================
+
+step 1: generate two vfs on the target pf port (i.e. 0000:85:00.0):
+
+        echo 2 > /sys/bus/pci/devices/0000\:85\:00.0/sriov_numvfs
+        
+step 2: bind the two vfs to pci-stub:
+
+        echo "8086 10ed" > /sys/bus/pci/drivers/pci-stub/new_id
+        echo 0000:85:10.0 > /sys/bus/pci/devices/0000:85:10.0/driver/unbind
+        echo 0000:85:10.0 > /sys/bus/pci/drivers/pci-stub/bind
+        echo 0000:85:10.2 > /sys/bus/pci/devices/0000:85:10.2/driver/unbind
+        echo 0000:85:10.2 > /sys/bus/pci/drivers/pci-stub/bind
+
+step 3: passthrough vf 0 to vm0 and start vm0:
+
+        taskset -c 20,21,22,23 /usr/local/qemu-2.4.0/x86_64-softmmu/qemu-system-x86_64 \
+        -name vm0 -enable-kvm -chardev socket,path=/tmp/vm0_qga0.sock,server,nowait,id=vm0_qga0 \
+        -device virtio-serial -device virtserialport,chardev=vm0_qga0,name=org.qemu.guest_agent.0 \
+        -daemonize -monitor unix:/tmp/vm0_monitor.sock,server,nowait \
+        -net nic,vlan=0,macaddr=00:00:00:e2:4f:fb,addr=1f \
+        -net user,vlan=0,hostfwd=tcp:10.239.128.125:6064-:22 \
+        -device pci-assign,host=85:10.0,id=pt_0 -cpu host -smp 4 -m 6144 \
+        -object memory-backend-file,id=mem,size=6144M,mem-path=/mnt/huge,share=on \
+        -numa node,memdev=mem -mem-prealloc -drive 
+ file=/home/img/vm0.img -vnc :4
+
+step 4: passthrough vf 1 to vm1 and start vm1:
+
+        taskset -c 30,31,32,33 /usr/local/qemu-2.4.0/x86_64-softmmu/qemu-system-x86_64  \
+        -name vm1 -enable-kvm -chardev socket,path=/tmp/vm1_qga0.sock,server,nowait,id=vm1_qga0 \
+        -device virtio-serial -device virtserialport,chardev=vm1_qga0,name=org.qemu.guest_agent.0 \
+        -daemonize -monitor unix:/tmp/vm1_monitor.sock,server,nowait \
+        -net nic,vlan=0,macaddr=00:00:00:7b:d5:cb,addr=1f \
+        -net user,vlan=0,hostfwd=tcp:10.239.128.125:6126-:22 \
+        -device pci-assign,host=85:10.2,id=pt_0 -cpu host -smp 4 -m 6144 \
+        -object memory-backend-file,id=mem,size=6144M,mem-path=/mnt/huge,share=on \
+        -numa node,memdev=mem -mem-prealloc -drive 
+ file=/home/img/vm1.img -vnc :5
+
+
+Test Case1: test_2vf_d2d_pktgen_stream
+===========================================
+both vfs in the two vms using the dpdk driver, send stream from vf1 in
+vm1 by dpdk pktgen to vf in vm0, and verify the vf on vm0 can receive stream.
+
+step 1: run testpmd on vm0:
+
+        ./x86_64-native-linuxapp-gcc/app/testpmd -c 0x7 -n 1  -- -i

+
+step 5: send stream by pkt-gen on vm1:
+
+        ./app/app/x86_64-native-linuxapp-gcc/app/pktgen -c 0xf -n 2 
+ --proc-type auto -- -P -T -m '1.0' -s P:flow.pcap
+        
+step 6: verify vf 0 receive status on vm0: Rx-packets > 0
