The destination port is the adjacent port from the +enabled portmask, that is, if the first four ports are enabled (portmask 0x3), ports 0 and 1 forward +into each other. Also, the MAC addresses are affected as follows: + +- The source MAC address is replaced by the TX port MAC address +- The destination MAC address is replaced by 02:00:00:00:00:TX_PORT_ID + +Prerequisites +============= + +If using vfio the kernel must be >= 3.6+ and VT-d must be enabled in bios.When +using vfio, use the following commands to load the vfio driver and bind it +to the device under test:: + + modprobe vfio + modprobe vfio-pci + usertools/dpdk-devbind.py --bind=vfio-pci device_bus_id + +The application requires a number of command line options:: + + ./build/l2fwd-jobstats [EAL options] -- -p PORTMASK [-q NQ] [-l] + +The ``l2fwd-jobstats`` application is run with EAL parameters and parameters for +the application itself. For details about the EAL parameters, see the relevant +DPDK **Getting Started Guide**. This application supports three parameters for +itself. + +- p PORTMASK: A hexadecimal bitmask of the ports to configure +- q NQ: A number of queues (=ports) per lcore (default is 1) +- l: Use locale thousands separator when formatting big numbers. + +Test Case: L2fwd jobstats check +================================================ + +Assume port 0 and 1 are connected to the traffic generator, to run the test +application in linuxapp environment with 4 lcores, 2 ports and 2 RX queues +per lcore:: + + ./examples/l2fwd-jobstats/build/l2fwd-jobstats -c 0x03 -n 4 -- -q 2 -p 0x03 -l + +Then send 100, 000 packet to port 0 and 100, 000 packets to port 1, check the +NIC packets number reported by sample is the same with what we set at the packet +generator side. -- 2.17.2
