+SRIOV and InterVM Communication
+===============================
+
+Some applications such as pipelining of virtual appliances and traffic
+mirroring to virtual appliances require the high performance InterVM
+communications.
+
+The testpmd application is used to configure traffic mirroring, PF VM receive
+mode, PFUTA hash table and control traffic to a VF for inter-VM communication.
+
+The 82599 supports four separate mirroring rules, each associated with a
+destination pool. Each rule is programmed with one of the four mirroring types:
+
+1. Pool mirroring: reflect all the packets received to a pool from the network.
+2. Uplink port mirroring: reflect all the traffic received from the network.
+3. Downlink port mirroring: reflect all the traffic transmitted to the
+ network.
+4. VLAN mirroring: reflect all the traffic received from the network
+ in a set of given VLANs (either from the network or from local VMs).
+
+
+Prerequisites for all 2VMs cases/Mirror 2VMs cases
+==================================================
+
+Create two VF interface VF0 and VF1 from one PF interface and then attach them
+to VM0 and VM1. Suppose PF is 0000:08:00.0.Below are commands which can be
+used to generate 2VFs and make them in pci-stub modes.::
+
+ ./tools/pci_unbind.py --bind=igb_uio 0000:08:00.0
+ echo 2 > /sys/bus/pci/devices/0000\:08\:00.0/max_vfs
+ echo "8086 10ed" > /sys/bus/pci/drivers/pci-stub/new_id
+ echo 0000:08:10.0 >/sys/bus/pci/devices/0000\:08\:10.0/driver/unbind
+ echo 0000:08:10.2 >/sys/bus/pci/devices/0000\:08\:10.2/driver/unbind
+ echo 0000:08:10.0 >/sys/bus/pci/drivers/pci-stub/bind
+ echo 0000:08:10.0 >/sys/bus/pci/drivers/pci-stub/bind
+
+Start PF driver on the Host and skip the VFs.::
+
+ ./x86_64-default-linuxapp-gcc/app/testpmd -c f -n 4 -b 0000:08:10.0 -b 0000:08:10.2 -- -i
+
+For VM0 start up command, you can refer to below command.::
+
+ qemu-system-x86_64 -name vm0 -enable-kvm -m 2048 -smp 4 -cpu host -drive file=/root/Downloads/vm0.img -net nic,macaddr=00:00:00:00:00:01 -net tap,script=/etc/qemu-ifup -device pci-assign,host=08:10.0 -vnc :1 --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
+
+Similar for VM1, please refer to below command for VM1::
+
+ qemu-system-x86_64 -name vm1 -enable-kvm -m 2048 -smp 4 -cpu host -drive file=/root/Downloads/vm1.img -net nic,macaddr=00:00:00:00:00:02 -net tap,script=/etc/qemu-ifup -device pci-assign,host=08:10.2 -vnc :4 -daemonize
+
+If you want to run all common 2VM cases, please run testpmd on VM0 and VM1 and
+start traffic forward on the VM hosts. Some specific prerequisites need to be
+set up in each case::
+
+ VF0 ./x86_64-default-linuxapp-gcc/app/testpmd -c f -n 4 -- -i
+ VF0 testpmd-> set fwd rxonly
+ VF0 testpmd-> start
+
+ VF1 ./x86_64-default-linuxapp-gcc/app/testpmd -c f -n 4 -- -i
+ VF1 testpmd-> set fwd mac
+ VF1 testpmd-> start
+
+Test Case1: InterVM communication test on 2VMs
+==============================================
+
+Set the VF0 destination mac address to VF1 mac address, packets send from VF0
+will be forwarded to VF1 and then send out::
+
+ VF1 ./x86_64-default-linuxapp-gcc/app/testpmd -c f -n 4 -- -i
+ VF1 testpmd-> show port info 0
+ VF1 testpmd-> set fwd mac
+ VF1 testpmd-> start
+
+ VF0 ./x86_64-default-linuxapp-gcc/app/testpmd -c f -n 4 -- --eth-peer=0,"VF1 mac" -i
+ VF0 testpmd-> set fwd mac
+ VF0 testpmd-> start
+
+Send 10 packets with VF0 mac address and make sure the packets will be
+forwarded by VF1.
+
+Test Case2: Mirror Traffic between 2VMs with Pool mirroring

+
+ PF testpmd-> set port 0 mirror-rule 0 downlink-mirror dst-pool 1 on
+
+Make sure VM1 in receive only mode, VM0 send 16 packets, and verify the VM0
+packets has been mirrored to VM1::
+
+ VF1 testpmd-> set fwd rxonly
+ VF1 testpmd-> start
+ VF0 testpmd-> start tx_first
+
+Note: don't let VF1 fwd packets since downlink mirror will mirror back the
+packets to received packets, which will be an infinite loop.
+
+After test need reset mirror rule::
+
+ PF testpmd-> reset port 0 mirror-rule 0
+
+Test Case5: Mirror Traffic between VMs with Vlan mirroring

+
+ VF1 testpmd-> set fwd rxonly
+ VF1 testpmd-> start
+ VF0 testpmd-> start tx_first
+
+Note: don't let VF1 fwd packets since downlink mirror will mirror back the

+Send 10 packets with dst mac 00:11:22:33:44:55 to VF0 and make sure VF0 will
+receive the packets.
+
+Add another exact destination mac address on VF0::
+
+ PF testpmd-> mac_addr add port 0 vf 0 00:55:44:33:22:11
+
+Send 10 packets with dst mac 00:55:44:33:22:11 to VF0 and make sure VF0 will
+receive the packets.
+
+After test need restart PF and VF for clear exact mac addresss, first quit VF,
+then quit PF.
+
+Test Case10: Enable/Disable one uta MAC address on VF
+=====================================================
+
+Enable PF promisc mode and enable VF0 accept uta packets::
+
+ PF testpmd-> set promisc 0 on
+ PF testpmd-> set port 0 vf 0 rxmode ROPE on

+Test Case22: Scaling Uplink Mirror & Downlink Mirror on 4VFs
+============================================================
+
+Make sure prerequisites for scaling 4VFs per 1PF is set up.
+
+Add 2 mirror rules that will mirror all income traffic to VM2, all outcome
+traffic to VM3. Make sure VM2 and VM3 rxonly::

+Test Case24: Scaling InterVM communication on 4VFs
+==================================================
+
+Set the VF0 destination mac address to VF1 mac address, packets send from VF0
+will be forwarded to VF1 and then send out. Similar for VF2 and VF3::
+
+ VF1 ./x86_64-default-linuxapp-gcc/app/testpmd -c f -n 4 -- -i
+ VF1 testpmd-> show port info 0
+ VF1 testpmd-> set fwd mac

+ VF2 ./x86_64-default-linuxapp-gcc/app/testpmd -c f -n 4 -- --eth-peer=0,"VF3 mac" -i
+ VF2 testpmd-> set fwd mac
+ VF2 testpmd-> start
+
+Send 2 flows, one with VF0 mac address and make sure the packets will be
+forwarded by VF1, another with VF2 mac address and make sure the packets will
+be forwarded by VF3.
