The stats shows\n+received/send packets and packets dropped or failed to copy.\n+\n+In order to run the hardware copy application, the copying device\n+needs to be bound to user-space IO driver.\n+\n+Refer to the \"DMAdev library\" chapter in the \"Programmers guide\" for information\n+on using the library.\n+\n+The application requires a number of command line options:\n+\n+.. code-block:: console\n+\n+ ./<build_dir>/examples/dpdk-dma [EAL options] -- [-p MASK] [-q NQ] [-s RS] [-c <sw|hw>]\n+ [--[no-]mac-updating] [-b BS] [-f FS] [-i SI]\n+\n+where,\n+\n+* p MASK: A hexadecimal bitmask of the ports to configure (default is all)\n+\n+* q NQ: Number of Rx queues used per port equivalent to DMA channels\n+ per port (default is 1)\n+\n+* c CT: Performed packet copy type: software (sw) or hardware using\n+ DMA (hw) (default is hw)\n+\n+* s RS: Size of dmadev descriptor ring for hardware copy mode or rte_ring for\n+ software copy mode (default is 2048)\n+\n+* --[no-]mac-updating: Whether MAC address of packets should be changed\n+ or not (default is mac-updating)\n+\n+* b BS: set the DMA batch size\n+\n+* f FS: set the max frame size\n+\n+* i SI: set the interval, in second, between statistics prints (default is 1)\n+\n+The application can be launched in various configurations depending on\n+provided parameters. The app can use up to 2 lcores: one of them receives\n+incoming traffic and makes a copy of each packet. The second lcore then\n+updates MAC address and sends the copy. If one lcore per port is used,\n+both operations are done sequentially. For each configuration an additional\n+lcore is needed since the main lcore does not handle traffic but is\n+responsible for configuration, statistics printing and safe shutdown of\n+all ports and devices.\n+\n+The application can use a maximum of 8 ports.\n+\n+To run the application in a Linux environment with 3 lcores (the main lcore,\n+plus two forwarding cores), a single port (port 0), software copying and MAC\n+updating issue the command:\n+\n+ $ ./<build_dir>/examples/dpdk-dma -l 0-2 -n 2 -- -p 0x1 --mac-updating -c sw\n+\n+To run the application in a Linux environment with 2 lcores (the main lcore,\n+plus one forwarding core), 2 ports (ports 0 and 1), hardware copying and no MAC\n+updating issue the command:\n+\n+ $ ./<build_dir>/examples/dpdk-dma -l 0-1 -n 1 -- -p 0x3 --no-mac-updating -c hw\n+\n+Prerequisites\n+=============\n+\n+Test flow\n+---------\n+ \n+NIC RX -> copy packet -> free original -> update mac addresses -> NIC TX\n+\n+General set up\n+--------------\n+1.
