Subject: [dts] [PATCH] add vf mac filter test script, plan and config file

Signed-off-by: Qian Xu <qian.q.xu@intel.com>

This patch is to add 3 file:
1. configure file for vf_macfilter: the vm settings and qemu parameters 2. vf mac filter test plan: describe 2 cases, each case may check 2-3 points for the positive and negative inputs.
3. vf mac filter test script: implement 2 cases according to the test plan. Note: fvl vf mac_addr add is not supported now, so 1 case will be failed.

+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::

+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

+0000:81:02.0 '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::
+

+
+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 0000:81:0a.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

+0000:81:0a.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

+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 set fwd mac 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.
