The stats shows +received/send packets and packets dropped or failed to copy. + +In order to run the hardware copy application, the copying device +needs to be bound to user-space IO driver. + +Refer to the "DMAdev library" chapter in the "Programmers guide" for information +on using the library. + +The application requires a number of command line options: + +.. code-block:: console + + .//examples/dpdk-dma [EAL options] -- [-p MASK] [-q NQ] [-s RS] [-c ] + [--[no-]mac-updating] [-b BS] [-f FS] [-i SI] + +where, + +* p MASK: A hexadecimal bitmask of the ports to configure (default is all) + +* q NQ: Number of Rx queues used per port equivalent to DMA channels + per port (default is 1) + +* c CT: Performed packet copy type: software (sw) or hardware using + DMA (hw) (default is hw) + +* s RS: Size of dmadev descriptor ring for hardware copy mode or rte_ring for + software copy mode (default is 2048) + +* --[no-]mac-updating: Whether MAC address of packets should be changed + or not (default is mac-updating) + +* b BS: set the DMA batch size + +* f FS: set the max frame size + +* i SI: set the interval, in second, between statistics prints (default is 1) + +The application can be launched in various configurations depending on +provided parameters.
