+
+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: copy $DTS/dep/tgen.tgz to guest from which send the stream
+
+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 --txqflags=0
+
+step 2: set rxonly and start on vm0:
+
+ set fwd rxonly
+ start
+
+step 3: copy pktgen-dpdk tarball to vm1:
+
+ scp tgen.tgz to vm1
+ tar xvf tgen.tgz
+
+step 4: generate pcap file on vm1:
+
+ Context: [Ether(dst="52:54:12:45:67:10", src="52:54:12:45:67:11")/IP()/Raw(load='X'\*46)]
+
+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 equal to send packets count, 100
+
+ show port stats 0
+ ######################## NIC statistics for port 0 ########################
+ RX-packets: 100 RX-missed: 0 RX-bytes: 6000
+ RX-errors: 0
+ RX-nombuf: 0
+ TX-packets: 0 TX-errors: 0 TX-bytes: 0
+ ############################################################################
+
+Test Case2: test_2vf_d2k_pktgen_stream
+======================================
+step 1: bind vf to kernel driver on vm0
+
+step 2: start up vf interface and using tcpdump to capature received packets
+
+step 3: copy pktgen-dpdk tarball to vm1:
+
+ scp tgen.tgz to vm1
+ tar xvf tgen.tgz
+
+step 4: generate pcap file on vm1:
+
+ Context: [Ether(dst="52:54:12:45:67:10", src="52:54:12:45:67:11")/IP()/Raw(load='X'\*46)]
+
+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 equal to send packets count, 100
+
+Test Case3: test_2vf_k2d_scapy_stream
+======================================
+step 1: run testpmd on vm0:
+
+ ./x86_64-native-linuxapp-gcc/app/testpmd -c 0x7 -n 1 -- -i --txqflags=0
+
+step 2: set rxonly and start on vm0:
+
+ set fwd rxonly
+ start
+
+step 3: bind vf to kernel driver on vm0
+
+step 4: using scapy to send packets
+
+step 5:verify vf 0 receive status on vm0: Rx-packets equal to send packets count, 100
+
+ show port stats 0
+ ######################## NIC statistics for port 0 ########################
+ RX-packets: 100 RX-missed: 0 RX-bytes: 6000

Abstract:
This suite adds three cases totally for vf to vf bridge
test suite, the test scenario details see the test plan ,
which named "0002-virt-vf-to-vf-nic-bridge-test-plan.patch".
Test Case1: test_2vf_d2d_pktgen_stream
use pktgen-dpdk as packet generator in first vm, and
use pmd driver on another vm
Test Case2: test_2vf_d2k_pktgen_stream
use pktgen-dpdk as packet generator in first vm, and
use kernel driver on another vm
Test Case3: test_2vf_k2d_scapy_stream
use scapy as packet generator in first vm, and
use pmd driver on another vm
v3: using default pktgen as packet generator
update: settle env prepare to set_up for debug require
