- sudo ./testpmd -l 0-3 -n 4 -- -i --portmask=0x1 --nb-cores=2
+ sudo ./dpdk-testpmd -l 0-3 -n 4 -- -i --portmask=0x1 --nb-cores=2
The command line options are:
* ``--nb-cores=N``
Set the number of forwarding cores,
- where 1 <= N <= "number of cores" or ``CONFIG_RTE_MAX_LCORE`` from the configuration file.
+ where 1 <= N <= "number of cores" or ``RTE_MAX_LCORE`` from the configuration file.
The default value is 1.
* ``--nb-ports=N``
Set the number of forwarding ports,
- where 1 <= N <= "number of ports" on the board or ``CONFIG_RTE_MAX_ETHPORTS`` from the configuration file.
+ where 1 <= N <= "number of ports" on the board or ``RTE_MAX_ETHPORTS`` from the configuration file.
The default value is the number of ports on the board.
* ``--coremask=0xXX``
Set the hexadecimal bitmask of the cores running the packet forwarding test.
- The master lcore is reserved for command line parsing only and cannot be masked on for packet forwarding.
+ The main lcore is reserved for command line parsing only and cannot be masked on for packet forwarding.
* ``--portmask=0xXX``
* ``--eth-peer=N,XX:XX:XX:XX:XX:XX``
Set the MAC address ``XX:XX:XX:XX:XX:XX`` of the peer port N,
- where 0 <= N < ``CONFIG_RTE_MAX_ETHPORTS`` from the configuration file.
+ where 0 <= N < ``RTE_MAX_ETHPORTS``.
* ``--tx-ip=SRC,DST``
If set to 0, driver default is used if defined. Else, if driver
default is not defined, default of 32 is used.
+* ``--flowgen-clones=N``
+
+ Set the number of each packet clones to be sent in `flowgen` mode.
+ Sending clones reduces host CPU load on creating packets and may help
+ in testing extreme speeds or maxing out Tx packet performance.
+ N should be not zero, but less than 'burst' parameter.
+
* ``--mbcache=N``
Set the cache of mbuf memory pools to N, where 0 <= N <= 512.
Don't flush the RX streams before starting forwarding. Used mainly with the PCAP PMD.
+* ``--rxoffs=X[,Y]``
+
+ Set the offsets of packet segments on receiving if split
+ feature is engaged. Affects only the queues configured
+ with split offloads (currently BUFFER_SPLIT is supported only).
+
* ``--rxpkts=X[,Y]``
Set the length of segments to scatter packets on receiving if split
