+VEB Switch and floating VEB Test Plan 
+=====================================
+
+VEB Switching Introduction
+==========================
+
+IEEE EVB tutorial: 
+http://www.ieee802.org/802_tutorials/2009-11
+/evb-tutorial-draft-20091116_v09.pdf
+
+Virtual Ethernet Bridge (VEB) - This is an IEEE EVB term. A VEB is a VLAN 
+Bridge internal to Fortville that bridges the traffic of multiple VSIs over
+ an internal virtual network. 
+
+Virtual Ethernet Port Aggregator (VEPA) - This is an IEEE EVB term. A VEPA
+multiplexes the traffic of one or more VSIs onto a single Fortville Ethernet
+port. The biggest difference between a VEB and a VEPA is that a VEB can
+switch packets internally between VSIs, whereas a VEPA cannot. 
+
+Virtual Station Interface (VSI) - This is an IEEE EVB term that defines 
+the properties of a virtual machine's (or a physical machine's) connection 
+to the network. Each downstream v-port on a Fortville VEB or VEPA defines 
+a VSI. A standards-based definition of VSI properties enables network 
+management tools to perform virtual machine migration and associated network 
+re-configuration in a vendor-neutral manner.
+
+My understanding of VEB is that it's an in-NIC switch(MAC/VLAN), and it can 
+support VF->VF, PF->VF, VF->PF packet forwarding according to the NIC internal 
+switch. It's similar as Niantic's SRIOV switch.
+
+Floating VEB Introduction
+=========================
+
+Floating VEB is based on VEB Switching. It will address 2 problems:
+
+Dependency on PF: When the physical port is link down, the functionality of 
+the VEB/VEPA will not work normally. Even only data forwarding between the VF 
+is required, one PF port will be wasted to create the related VEB.
+
+Ensure all the traffic from VF can only forwarding within the VFs connect 
+to the floating VEB, cannot forward to the outside world.
+
+Prerequisites for VEB testing
+=============================
+
+1. Get the pci device id of DUT, for example::
+
+    ./dpdk-devbind.py --st
+    0000:05:00.0 'Ethernet Controller X710 for 10GbE SFP+' if=ens785f0 drv=i40e 
+    unused=
+    
+2.1  Host PF in kernel driver. Create 2 VFs from 1 PF with kernel driver, 
+     and set the VF MAC address at PF::
+
+    echo 2 > /sys/bus/pci/devices/0000\:05\:00.0/sriov_numvfs
+    ./dpdk-devbind.py --st
+
+    0000:05:02.0 'XL710/X710 Virtual Function' unused=
+    0000:05:02.1 'XL710/X710 Virtual Function' unused=
+
+    ip link set ens785f0 vf 0 mac 00:11:22:33:44:11
+    ip link set ens785f0 vf 1 mac 00:11:22:33:44:12
+
+2.2  Host PF in DPDK driver. Create 2VFs from 1 PF with dpdk driver:: 
+    
+    ./dpdk-devbind.py -b igb_uio 05:00.0 
+    echo 2 >/sys/bus/pci/devices/0000:05:00.0/max_vfs
+    ./dpdk-devbind.py --st
+    0000:05:02.0 'XL710/X710 Virtual Function' unused=i40evf,igb_uio
+    0000:05:02.1 'XL710/X710 Virtual Function' unused=i40evf,igb_uio
+
+3. Bind the VFs to dpdk driver::
+
+    ./tools/dpdk-devbind.py -b igb_uio 05:02.0 05:02.1
+
+4. Reserve huge pages memory(before using DPDK)::
+
+    echo 4096 > /sys/devices/system/node/node0/hugepages/hugepages-2048kB
+    /nr_hugepages 
+    mkdir /mnt/huge  
+    mount -t hugetlbfs nodev /mnt/huge    
+
+
+Test Case1: Floating VEB inter VF-VF 
+=======================================================
+
+Summary: 1 DPDK PF, then create 2VF, PF in the host running dpdk testpmd, 
+and VF0 are running dpdk testpmd, VF0 send traffic, and set the packet's 
+DEST MAC to VF1, check if VF1 can receive the packets. Check Inter VF-VF 
+MAC switch when PF is link down as well as up.
+
+Launch PF testpmd::
+   ./x86_64-native-linuxapp-gcc/app/testpmd -c 0xf -n 4 --socket-mem 1024,1024
+   -w 05:00.0,enable_floating_veb=1 --file-prefix=test1 -- -i
+
+2. In the host, run testpmd with floating parameters and make the link down::
+
+   ./x86_64-native-linuxapp-gcc/app/testpmd -c 0xf -n 4 --socket-mem 1024,1024
+   -w 05:00.0,enable_floating_veb=1 --file-prefix=test1 -- -i
+   testpmd> port start all
+   testpmd> show port info all
+
+3. In VM1, run testpmd::
+
+   ./x86_64-native-linuxapp-gcc/app/testpmd -c 0xf0 -n 4 --socket-mem 1024,1024
+   -w 05:02.0 --file-prefix=test2 -- -i --crc-strip 
+   testpmd>mac_addr add 0 vf1_mac_address
+   testpmd>set fwd rxonly
+   testpmd>start
+   testpmd>show port stats all
+   
+  In VM2, run testpmd::
+
+ ./testpmd -c 0xf00 -n 4 --socket-mem 1024,1024 -w 05:02.1 --file-prefix=test3
+ -- -i --crc-strip --eth-peer=0,vf1_mac_address
+ testpmd>set fwd txonly
+ testpmd>start
+ testpmd>show port stats all
+
+4. check if VF1 can get all the packets. Check the packet content is no 
+   corrupted. RX-packets=TX-packets, but there is a little RX-error. 
+   RF receive no packets.
+
+5. Set "testpmd> port stop all" and "testpmd> start" in step2, 
+   then run the step3-4 again. same result.
+
+
+Test Case2: Floating VEB PF can't get traffic from VF    
+================================================================
+DPDK PF, then create 1VF, PF in the host running dpdk testpmd, 
+send traffic from PF to VF0, VF0 can't receive any packets; 
+send traffic from VF0 to PF, PF can't receive any packets either.
+ 
+
+1. In host, launch testpmd::
+
+   ./testpmd -c 0x3 -n 4 -w 82:00.0,enable_floating_veb=1 -- -i
+   testpmd> set fwd rxonly
+   testpmd> port start all
+   testpmd> start
+   testpmd> show port stats all
+
+3. In VM1, run testpmd::
+
+   ./testpmd -c 0x3 -n 4 -- -i --eth-peer=0,pf_mac_addr
+   testpmd>set fwd txonly
+   testpmd>start
+   testpmd>show port stats all
+
+4. Check if PF can not get any packets, so VF1->PF is not working. 
+
+5. Set "testpmd> port stop all" in step2, then run the test case again.
+   Same result.
+
+
+
+Test Case2-2 Floating VEB VF can't receive traffic from outside world 
+======================================================
+
+DPDK PF, then create 1VF, send traffic from tester to VF1, 
+in floating mode, check VF1 can't receive traffic from tester.
+
+1. Start VM1 with VF1, see the prerequisite part.
+
+2. In host, launch testpmd::
+
+   ./testpmd -c 0x3 -n 4 -w 82:00.0,enable_floating_veb=1 -- -i 
+   testpmd> set fwd mac
+   testpmd> port start all
+   testpmd> start
+   testpmd> show port stats all
+   
+
+   In VM1, run testpmd:
+
+   ./testpmd -c 0x3 -n 4 -- -i 
+    testpmd>show port info all    //get VF_mac_address
+    testpmd>set fwd rxonly
+    testpmd>start
+    testpmd>show port stats all
+
+   In tester, run scapy
+
+   packet=Ether(dst="VF_mac_address")/IP()/UDP()/Raw('x'*20)
+   sendp(packet,iface="enp132s0f0")
+   
+3. Check if VF1 can not get any packets, so tester->VF1 is not working.
+4. Set "testpmd> port stop all" in step2 in Host, then run the test case 
+   again. same result.PF can't receive any packets. 
+
+
+Test Case3: Floating VEB VF can not communicate with legacy VEB VF 
+======================================================
+
+Summary: DPDK PF, then create 4VFs and 4VMs, VF1,VF3,VF4, floating VEB; 
+VF2, lagecy VEB. Make PF link down(the cable can be pluged out), 
+VFs in VMs are running dpdk testpmd.
+1. VF1 send traffic, and set the packet's DEST MAC to VF2, 
+   check VF2 can not receive the packets. 
+2. VF1 send traffic, and set the packet's DEST MAC to VF3, 
+   check VF3 can receive the packets. 
+3. VF4 send traffic, and set the packet's DEST MAC to VF3, 
+   check VF3 can receive the packets.
+4. VF2 send traffic, and set the packet's DEST MAC to VF1, 
+   check VF1 can not receive the packets. 
+Check Inter-VM VF-VF MAC switch when PF is link down as well as up.
+
+Launch PF testpmd:: 
+  ./testpmd -c 0x3 -n 4 
+   -w "82:00.0,enable_floating_veb=1,floating_veb_list=0;2-3" -- -i
+
+1. Start VM1 with VF1, VM2 with VF2, VM3 with VF3, 
+   VM4 with VF4,see the prerequisite part.
+
+2. In the host, run testpmd with floating parameters and make the link down::
+
+   ./testpmd -c 0x3 -n 4 
+    -w "82:00.0,enable_floating_veb=1,floating_veb_list=0;2-3" -- -i     
+    //VF1 and VF3 in floating VEB, VF2 in legacy VEB
+   
+   testpmd> port stop all     
+   //this step should be executed after vf running testpmd.
+    
+   testpmd> show port info all
+
+3. VF1 send traffic, and set the packet's DEST MAC to VF2, 
+   check VF2 can not receive the packets.
+
+    In VM2, run testpmd::
+
+    ./testpmd -c 0x3 -n 4 -- -i 
+    testpmd>set fwd rxonly
+    testpmd>mac_addr add 0 vf2_mac_address     //set the vf2_mac_address
+    testpmd>start
+    testpmd>show port stats all
+   
+    In VM1, run testpmd::
+
+    ./testpmd -c 0x3 -n 4 -- -i --eth-peer=0,vf2_mac_address
+    testpmd>set fwd txonly
+    testpmd>start
+    testpmd>show port stats all
+
+    Check VF2 can not get any packets, so VF1->VF2 is not working.
+
+4. VF1 send traffic, and set the packet's DEST MAC to VF3, 
+   check VF3 can receive the packets.
+
+    In VM3, run testpmd::
+
+    ./testpmd -c 0x3 -n 4 -- -i 
+    testpmd>set fwd rxonly
+    testpmd>show port info all     //get the vf3_mac_address
+    testpmd>start
+    testpmd>show port stats all
+
+    In VM1, run testpmd::
+
+    ./testpmd -c 0x3 -n 4 -- -i --eth-peer=0,vf3_mac_address
+    testpmd>set fwd txonly
+    testpmd>start
+    testpmd>show port stats all
+
+ Check VF3 can get all the packets. Check the packet content is no corrupted.
+ so VF1->VF2 is working.
+
+5. VF2 send traffic, and set the packet's DEST MAC to VF1, 
+   check VF1 can not receive the packets. 
+
+    In VM1, run testpmd::
+
+    ./testpmd -c 0x3 -n 4 -- -i 
+    testpmd>set fwd rxonly
+    testpmd>show port info all     //get the vf1_mac_address
+    testpmd>start
+    testpmd>show port stats all
+
+    In VM2, run testpmd::
+
+    ./testpmd -c 0x3 -n 4 -- -i --eth-peer=0,vf1_mac_address
+    testpmd>set fwd txonly
+    testpmd>start
+    testpmd>show port stats all
+
+    Check VF1 can not get any packets, so VF2->VF1 is not working.
+
+6. Set "testpmd> port start all" and "testpmd> start" in step2, 
+   then run the step3-5 again. same result.
+
+
+Test Case4: PF can't get traffic from Floating VEB VF, but PF can get traffic 
+================================================================
+from legacy VEB VF.
+================================================================
+DPDK PF, then create 2VFs, VF0 is in floating VEB, VF1 is in legacy VEB.
+1. Send traffic from VF0 to PF, then check PF will not see any traffic;
+2. Send traffic from VF1 to PF, then check PF will receive all the packets.
+3. send traffic from tester to VF0, check VF0 can't receive traffic from 
+   tester.
+4. send traffic from tester to VF1, check VF1 can receive all the traffic 
+   from tester.
+
+1. In host, launch testpmd::
+
+   ./testpmd -c 0x3 -n 4 
+    -w 82:00.0,enable_floating_veb=1,floating_veb_list=0 -- -i
