+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
+ testpmd> set fwd rxonly
+ testpmd> port start all
+ testpmd> start
+ testpmd> show port stats all
+
+3. In VF1, 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
+
+ Check PF can not get any packets, so VF1->PF is not working.
+
+4. In VF2, 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
+
+ Check PF can get all the packets, so VF2->PF is working.
+
+5. Set "testpmd> port stop all" in step2 in Host,
+ then run the test case again. same result.
+
+6. In host, launch testpmd::
+
+ ./testpmd -c 0x3 -n 4
+ -w 82:00.0,enable_floating_veb=1,floating_veb_list=0 -- -i
+ testpmd> set fwd mac
+ testpmd> port start all
+ testpmd> start
+ testpmd> show port stats all
+
+
+7. In VF1, run testpmd::
+
+ ./testpmd -c 0x3 -n 4 -- -i
+ testpmd>show port info all //get VF1_mac_address
+ testpmd>set fwd rxonly
+ testpmd>start
+ testpmd>show port stats all
+
+ In tester, run scapy
+
+ packet=Ether(dst="VF1_mac_address")/IP()/UDP()/Raw('x'*20)
+ sendp(packet,iface="enp132s0f0")
+
+ Check VF1 can not get any packets, so tester->VF1 is not working.
+
+8. In VF2, run testpmd::
+
+ ./testpmd -c 0x3 -n 4 -- -i
+ testpmd>show port info all //get VF2_mac_address
+ testpmd>set fwd rxonly
+ testpmd>start
+ testpmd>show port stats all
+
+ In tester, run scapy
+
+ packet=Ether(dst="VF2_mac_address")/IP()/UDP()/Raw('x'*20)
+ sendp(packet,iface="enp132s0f0")
+
+ Check VF1 can get all the packets, so tester->VF2 is working.
+
+5. Set "testpmd> port stop all" in step2 in Host, then run the test case again.
+ VF1 and VF2 cannot receive any packets. (because PF link down,
+ and PF can't receive any packets. so even if VF2 can't receive any packets.)
