The Soft NIC pipeline +is configurable through firmware (DPDK Packet Framework script). + +Prerequisites +============= +1. The DUT must have one 10G Ethernet port connected to a port on tester + that are controlled by the traffic generator:: + + dut_port_0 <---> tester_port_0 + + Assume the DUT 10G Ethernet port's pci device id is as the following:: + + dut_port_0 : "0000:05:00.0" + + Bind it to dpdk igb_uio driver:: + + ./usertools/dpdk-devbind.py -b igb_uio 05:00.0 + +2. Change ./drivers/net/softnic/firmware.cli to meet the specific test environment. + +3. Start softnic with following command line:: + + ./x86_64-native-linuxapp-gcc/app/testpmd -l 23-25 -n 4 \ + --vdev 'net_softnic0,firmware=./drivers/net/softnic/firmware.cli,cpu_id=1,conn_port=8086' \ + -- -i --forward-mode=softnic --portmask=0x2 + testpmd> start + + Or Start softnic with default hierarchy Qos with following command line:: + + ./x86_64-native-linuxapp-gcc/app/testpmd -l 23-25 -n 4 \ + --vdev 'net_softnic0,firmware=./drivers/net/softnic/firmware.cli,cpu_id=1,conn_port=8086' \ + -- -i --forward-mode=softnic --portmask=0x2 + testpmd> set port tm hierarchy default 1 + testpmd> start + +Test Case 1: softnic performance +================================ +1. Start softnic:: + + ./x86_64-native-linuxapp-gcc/app/testpmd -l 23-25 -n 4 \ + --vdev 'net_softnic0,firmware=./drivers/net/softnic/firmware.cli,cpu_id=1,conn_port=8086' \ + -- -i --forward-mode=softnic --portmask=0x2 + testpmd> start + +2. Send packet at line rate from traffic generator (IXIA or other) with packet size from 64~1518B. +3. Check performance number is same as the physical NIC's performance number, no performance drop. + +Test Case 2: shaping for pipe +============================= +1. The specifications of the default Hierarchical Scheduler are as follows: + + Root node (x1, level 0) + Subport node (x1, level 1) + Pipe node (x4096, level 2) + Traffic Class node (x16348, level 3) + Queue node (x65536, level 4) + +2. Start softnic with the default hierarchy Qos:: + + ./x86_64-native-linuxapp-gcc/app/testpmd -l 23-25 -n 4 \ + --vdev 'net_softnic0,firmware=./drivers/net/softnic/tm_firmware.cli,cpu_id=1,conn_port=8086' \ + -- -i --forward-mode=softnic --portmask=0x2 + testpmd> set port tm hierarchy default 1 + testpmd> start + +3. Send per flow traffic with 100% line rate, verify output flow rate is 1/4096 subport rate. + +Test Case 3: NAT +================ +1. Set SNAT with proto tcp test, edit nat_firmware.cli to change "table action" as below:: + + table action profile AP0 ipv4 offset 270 fwd nat src proto tcp + +(a). Start softnic:: + + ./x86_64-native-linuxapp-gcc/app/testpmd -l 23-25 -n 4 \ + --vdev 'net_softnic0,firmware=./drivers/net/softnic/nat_firmware.cli,cpu_id=1,conn_port=8086' \ + -- -i --forward-mode=softnic --portmask=0x2 + testpmd> start + +(b). Sent packet, verify the received packet's ipaddr and port was changed as expected. + +2. Set DNAT with proto tcp test, edit nat_firmware.cli to change "table action" as below:: + + table action profile AP0 ipv4 offset 270 fwd nat dst proto tcp + + Then re-run step (a) & step (b). + +3. Set SNAT with proto udp test, edit nat_firmware.cli to change "table action" as below:: + + table action profile AP0 ipv4 offset 270 fwd nat src proto udp + + Then re-run step (a) & step (b). + +4. Set DNAT with proto udp test, edit nat_firmware.cli to change "table action" as below:: + + table action profile AP0 ipv4 offset 270 fwd nat dst proto udp + + Then re-run step (a) & step (b). -- 2.14.3
