[dts] [PATCH v2] add vf mac filter test automation script and plan

Mon Jan 11 03:49:09 CET 2016
This patch will add vf test plan,script and config file.
VF MAC filter test case is as below:
1. Kernel PF using ip link set command to set VF
MAC address, then check mac filter works or not.
Also check negative case that sending packets
with wrong MAC to ensure mac filter works.
2. Kernel PF will not set MAC address for VF, VF
MAC address is randomly generated. Sending packets
to the VF mac address to ensure mac filter works.
Also using mac_addr add command in testpmd to add
a new mac address, then check if the packets with
this new mac address can be RX/TX. Also check traffic
with wrong MAC address will not be RXed.

+Test Case 1: test_kernel_2pf_2vf_1vm_iplink_macfilter
+=====================================================
+
+1. Get the pci device id of DUT, for example::
+
+./dpdk_nic_bind.py --st
+
+0000:81:00.0 'Ethernet Controller X710 for 10GbE SFP+' if=ens259f0 drv=i40e unused=
+0000:81:00.1 'Ethernet Controller X710 for 10GbE SFP+' if=ens259f1 drv=i40e unused=
+
+2. Create 2 VFs from 2 PFs, and set the VF MAC address at PF0::
+
+echo 1 > /sys/bus/pci/devices/0000\:81\:00.0/sriov_numvfs
+echo 1 > /sys/bus/pci/devices/0000\:81\:00.1/sriov_numvfs
+
+./dpdk_nic_bind.py --st
+0000:81:00.0 'Ethernet Controller X710 for 10GbE SFP+' if=ens259f0 drv=i40e unused=
+0000:81:00.1 'Ethernet Controller X710 for 10GbE SFP+' if=ens259f1 drv=i40e unused=
+0000:81:02.0 'XL710/X710 Virtual Function' unused=
+0000:81:0a.0 'XL710/X710 Virtual Function' unused=
+
+ip link set ens259f0 vf 0 mac 00:11:22:33:44:55
+
+3. Detach VFs from the host, bind them to pci-stub driver::
+
+/sbin/modprobe pci-stub
+
+using `lspci -nn|grep -i ethernet` got VF device id, for example "8086 154c",
+
+echo "8086 154c" > /sys/bus/pci/drivers/pci-stub/new_id
+echo 0000:81:02.0 > /sys/bus/pci/devices/0000:08:02.0/driver/unbind
+echo 0000:81:02.0 > /sys/bus/pci/drivers/pci-stub/bind
+
+echo "8086 154c" > /sys/bus/pci/drivers/pci-stub/new_id
+echo 0000:81:0a.0 > /sys/bus/pci/devices/0000:08:0a.0/driver/unbind
+echo 0000:81:0a.0 > /sys/bus/pci/drivers/pci-stub/bind
+
+or using the following more easy way,
+
+virsh nodedev-detach pci_0000_81_02_0;
+virsh nodedev-detach pci_0000_81_0a_0;
+
+./dpdk_nic_bind.py --st
+
+0000:81:00.0 'Ethernet Controller X710 for 10GbE SFP+' if=ens259f0 drv=i40e unused=
+0000:81:00.1 'Ethernet Controller X710 for 10GbE SFP+' if=ens259f1 drv=i40e unused=
+0000:81:02.0 'XL710/X710 Virtual Function' if= drv=pci-stub unused=
+0000:81:0a.0 'XL710/X710 Virtual Function' if= drv=pci-stub unused=
+
+it can be seen that VFs 81:02.0 & 81:0a.0 's driver is pci-stub.
+
+4. Passthrough VFs 81:02.0 & 81:0a.0 to vm0, and start vm0::
+
+/usr/bin/qemu-system-x86_64 -name vm0 -enable-kvm \
+-cpu host -smp 4 -m 2048 -drive file=/home/image/sriov-fc20-1.img -vnc :1 \
+-device pci-assign,host=81:02.0,id=pt_0 \
+-device pci-assign,host=81:0a.0,id=pt_1
+
+5. 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, enable CRC strip, disable promisc mode,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 -w 00:06.0 -w 00:07.0 -- -i --portmask=0x3 --txqflags=0
+
+testpmd> port stop all
+testpmd> port config all crc-strip on
+testpmd> port start all
+testpmd> set promisc all off
+testpmd> set fwd mac
+testpmd> start
+
+6. Use scapy to send 100 random packets with ip link set MAC to VF, verify the packets can be received by one
+VF and can be forward to another VF correctly.
+
+7. Also use scapy to send 100 random packets with a wrong MAC to VF, verify the packets can't be received by one
+VF and can be forward to another VF correctly.
+
+Test Case 2: test_kernel_2pf_2vf_1vm_mac_add_filter
+===================================================
+
+1. Get the pci device id of DUT, for example::
+
+./dpdk_nic_bind.py --st
+
+0000:81:00.0 'Ethernet Controller X710 for 10GbE SFP+' if=ens259f0 drv=i40e unused=
+0000:81:00.1 'Ethernet Controller X710 for 10GbE SFP+' if=ens259f1 drv=i40e unused=
+
+2. Create 2 VFs from 2 PFs, and don't set the VF MAC address at PF0::
+
+echo 1 > /sys/bus/pci/devices/0000\:81\:00.0/sriov_numvfs
+echo 1 > /sys/bus/pci/devices/0000\:81\:00.1/sriov_numvfs
+
+./dpdk_nic_bind.py --st
+0000:81:00.0 'Ethernet Controller X710 for 10GbE SFP+' if=ens259f0 drv=i40e unused=
+0000:81:00.1 'Ethernet Controller X710 for 10GbE SFP+' if=ens259f1 drv=i40e unused=
+0000:81:02.0 'XL710/X710 Virtual Function' unused=
+0000:81:0a.0 'XL710/X710 Virtual Function' unused=
+
+3. Detach VFs from the host, bind them to pci-stub driver::
+
+/sbin/modprobe pci-stub
+
+using `lspci -nn|grep -i ethernet` to get VF device id, for example "8086 154c",
+
+echo "8086 154c" > /sys/bus/pci/drivers/pci-stub/new_id
+echo 0000:81:02.0 > /sys/bus/pci/devices/0000:08:02.0/driver/unbind
+echo 0000:81:02.0 > /sys/bus/pci/drivers/pci-stub/bind
+
+echo "8086 154c" > /sys/bus/pci/drivers/pci-stub/new_id
+echo 0000:81:0a.0 > /sys/bus/pci/devices/0000:08:0a.0/driver/unbind
+echo 0000:81:0a.0 > /sys/bus/pci/drivers/pci-stub/bind
+
+or using the following more easy way,
+
+virsh nodedev-detach pci_0000_81_02_0;
+virsh nodedev-detach pci_0000_81_0a_0;
+
+./dpdk_nic_bind.py --st
+
+0000:81:00.0 'Ethernet Controller X710 for 10GbE SFP+' if=ens259f0 drv=i40e unused=
+0000:81:00.1 'Ethernet Controller X710 for 10GbE SFP+' if=ens259f1 drv=i40e unused=
+0000:81:02.0 'XL710/X710 Virtual Function' if= drv=pci-stub unused=
+0000:81:0a.0 'XL710/X710 Virtual Function' if= drv=pci-stub unused=
+
+it can be seen that VFs 81:02.0 & 81:0a.0 's driver is pci-stub.
+
+4. Passthrough VFs 81:02.0 & 81:0a.0 to vm0, and start vm0::
+
+/usr/bin/qemu-system-x86_64 -name vm0 -enable-kvm \
+-cpu host -smp 4 -m 2048 -drive file=/home/image/sriov-fc20-1.img -vnc :1 \
+-device pci-assign,host=81:02.0,id=pt_0 \
+-device pci-assign,host=81:0a.0,id=pt_1
+
+5. 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, enable CRC strip on VF, disable promisc mode, add a new MAC to VF0 and then start::
+
+./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 -w 00:06.0 -w 00:07.0 -- -i --portmask=0x3 --txqflags=0
+
+testpmd> port stop all
+testpmd> port config all crc-strip on
+testpmd> port start all
+testpmd> set promisc all off
+testpmd> mac_addr add 0 00:11:22:33:44:55
+testpmd> set fwd mac
+testpmd> start
+
+Note: In Jan,2016, i40e doesn't support mac_addr add operation, so the case will be failed for FVL/Fort park NICs.
+
+6. Use scapy to send 100 random packets with current VF0's MAC, verify the packets can be received by one
+VF and can be forward to another VF correctly.
+
+7. Use scapy to send 100 random packets with new added VF0's MAC, verify the packets can be received by one
+VF and can be forward to another VF correctly.
+
+8. Use scapy to send 100 random packets with a wrong MAC to VF0, verify the packets can't be received by one
+VF and can be forward to another VF correctly.
