To: dts
Send packets from tester ,at the same time, vf prot start/stop several time and check if it running right.
Three files added in the patch:
1, vf_port_start_stop.cfg: vm setting and qemu parameters.
2, vf_port_start_stop_test_plan.rst: test plan, describe 1 case.
3, TestSuite_vf_port_start_stop.py: implement one case according to the tes plan.

+
+Prerequisites
+=========================================
+
+Create Two VF interfaces from two kernel PF ineterfaces, and then attach them to VM. Suppose PF is 0000:04:00.0. Generate 2VFs using commands below and make them in pci-stub mods.
+
+1. Get the pci device id of DUT::
+
+ ./dpdk_nic_bind.py --st
+ 0000:04:00.0 '82599ES 10-Gigabit SFI/SFP+ Network Connection' if=ens261f0 drv=ixgbe unused=igb_uio
+
+2. Create 2 VFs from 2 PFs::
+
+ echo 2 > /sys/bus/pci/devices/0000\:04\:00.0/sriov_numvfs
+
+VFs 04:10.0 & 04:10.1 have been created::
+
+ ./dpdk_nic_bind.py --st
+ 0000:04:00.0 '82599ES 10-Gigabit SFI/SFP+ Network Connection' if=ens261f0 drv=ixgbe unused=
+ 0000:04:10.0 '82599 Ethernet Controller Virtual Function' if=enp4s16 drv=ixgbevf unused=
+ 0000:04:10.1 '82599 Ethernet Controller Virtual Function' if=enp4s16f1 drv=ixgbevf unused=
+
+3. detach VFs from the host, bind them to pci-stub driver::
+
+ /sbin/modprobe pci-stub
+ echo "8086 10ed" > /sys/bus/pci/drivers/pci-stub/new_id
+ echo 0000:04:10.0 > /sys/bus/pci/devices/0000\:04\:10.0/driver/unbind
+ echo 0000:04:10.0 > /sys/bus/pci/drivers/pci-stub/bind
+ echo 0000:04:10.1 > /sys/bus/pci/devices/0000\:04\:10.1/driver/unbind
+ echo 0000:04:10.1 > /sys/bus/pci/drivers/pci-stub/bind
+
+or using the following more easy way::
+
+ ./dpdk_nic_bind.py -b pci-stub 04:10.0 04:10.1
+
+it can be seen that VFs 04:10.0 & 04:10.1 's drv is pci-stub::
+
+ ./dpdk_nic_bind.py --st
+ 0000:04:00.0 '82599ES 10-Gigabit SFI/SFP+ Network Connection' if=ens261f0 drv=ixgbe unused=vfio-pci
+ 0000:04:10.0 '82599 Ethernet Controller Virtual Function' if= drv=pci-stub unused=ixgbevf,vfio-pci
+ 0000:04:10.1 '82599 Ethernet Controller Virtual Function' if= drv=pci-stub unused=ixgbevf,vfio-pci
+
+4. Do not forget bring up PFs::
+
+ ifconfig ens261f0 up
+
+Passthrough VFs 04:10.0 & 04:10.1 to vm0, and start vm0, you can refer to below command::
+
+ taskset -c 6-12 qemu-system-x86_64 \
+ -enable-kvm -m 8192 -smp 6 -cpu host -name dpdk15-vm1 \
+ -drive file=/home/image/fedora23.img \
+ -netdev tap,id=hostnet1,ifname=tap1,script=/etc/qemu-ifup,vhost=on \
+ -device rtl8139,netdev=hostnet1,id=net1,mac=52:54:01:6b:10:61,bus=pci.0,addr=0xa \
+ -device pci-assign,bus=pci.0,addr=0x6,host=04:10.0 \
+ -device pci-assign,bus=pci.0,addr=0x7,host=04:10.1 \
+ -vnc :11 -daemonize
+
+the /etc/qemu-ifup can be below script, need you to create first::
+
+ #!/bin/sh
+ set -x
+ switch=br0
+ if [ -n "$1" ];then
+ /usr/sbin/tunctl -u `whoami` -t $1
+ /sbin/ip link set $1 up
+ sleep 0.5s
+ /usr/sbin/brctl addif $switch $1
+ exit 0
+ else
+ echo "Error: no interface specified"
+ exit 1
+ fi
+
+Set up bridge br0 before create /etc/qemu-ifup, for example::
+
+ cd /etc/sysconfig/network-scripts
+ vim ifcfg-enp1s0f0
+
+ HWADDR=00:1e:67:fb:0f:d4
+ TYPE=Ethernet
+ NAME=enp1s0f0
+ ONBOOT=yes
+ DEVICE=enp1s0f0
+ NM_CONTROLLED=no
+ BRIDGE=br0
+
+ vim ifcfg-br0
+ TYPE=Bridge
+ DEVICE=br0
+ ONBOOT=yes
+ NM_CONTROLLED=no
+ BOOTPROTO=dhcp
+ HOSTNAME="dpdk-test58"
+
+Login vm0, got VFs pci device id in vm0, assume they are 00:06.0 &
+00:07.0, bind them to igb_uio driver, and then start testpmd, set it in
+mac forward mode::
+
+ ./tools/dpdk_nic_bind.py --bind=igb_uio 00:06.0 00:07.0
+ ./x86_64-native-linuxapp-gcc/app/testpmd -c 0x0f -n 4 -- -i
+ testpmd-> set fwd mac
+ testpmd-> start
+
+Test Case: port start/stop
+==========================
+Start send packets from tester , then start/stop ports several times ,verify if it running right.
+
+Commands could be used to start/stop ports refer to below::
+
+Start port::
+
+ testpmd-> port start all
+
+Stop port::
+
+ testpmd-> port stop all
+
+Send IP+UDP packet::
+
+ Ether(dst="0E:CB:F8:FF:4E:02", src="0E:CB:F8:FF:4E:02")/IP(src="127.0.0.2")/UDP()/("X"*46)
+
+Send IP+TCP packet::
+
+ Ether(dst="0E:CB:F8:FF:4E:02", src="0E:CB:F8:FF:4E:02")/IP(src="127.0.0.2")/TCP()/("X"*46)
+
+Send IP+SCTP packet::
+
+ Ether(dst="0E:CB:F8:FF:4E:02", src="0E:CB:F8:FF:4E:02")/IP(src="127.0.0.2")/SCTP()/("X"*46)
+
+Send IPv6+UDP packet::
+
+ Ether(dst="0E:CB:F8:FF:4E:02", src="0E:CB:F8:FF:4E:02")/IP(src="::2")/UDP()/("X"*46)
+
