+ This is the fastest possible forwarding operation as it does not access packets data.
+ This is the default mode.
+
+* ``mac``: Changes the source and the destination Ethernet addresses of packets before forwarding them.
+ Default application behaviour is to set source Ethernet address to that of the transmitting interface, and destination
+ address to a dummy value (set during init). The user may specify a target destination Ethernet address via the 'eth-peer' or
+ 'eth-peer-configfile' command-line options. It is not currently possible to specify a specific source Ethernet address.
+
+* ``macswap``: MAC swap forwarding mode.
+ Swaps the source and the destination Ethernet addresses of packets before forwarding them.
+
+* ``flowgen``: Multi-flow generation mode.
+ Originates a number of flows (with varying destination IP addresses), and terminate receive traffic.
+
+* ``rxonly``: Receives packets but doesn't transmit them.
+
+* ``txonly``: Generates and transmits packets without receiving any.
+
+* ``csum``: Changes the checksum field with hardware or software methods depending on the offload flags on the packet.
+
+* ``icmpecho``: Receives a burst of packets, lookup for IMCP echo requests and, if any, send back ICMP echo replies.
+
+* ``ieee1588``: Demonstrate L2 IEEE1588 V2 PTP timestamping for RX and TX. Requires ``CONFIG_RTE_LIBRTE_IEEE1588=y``.
+
+Note: TX timestamping is only available in the "Full Featured" TX path. To force ``testpmd`` into this mode set ``--txqflags=0``.

+
+Where:
+
+* ``ip|udp|tcp|sctp`` always relate to the inner layer.
+
+* ``outer-ip`` relates to the outer IP layer (only for IPv4) in the case where the packet is recognized
+ as a tunnel packet by the forwarding engine (vxlan, gre and ipip are
+ supported). See also the ``csum parse-tunnel`` command.
-Enable hardware insertion of checksum offload with a 4-bit mask, 0x0 - 0xF, in packets sent on a port:
+.. note::
-tx_checksum set (mask) (port_id)
+ Check the NIC Datasheet for hardware limits.
-The bits in the mask are:
+csum parse-tunnel
+~~~~~~~~~~~~~~~~~
-bit 0 - if set insert ip checksum offload
+Define how tunneled packets should be handled by the csum forward
+engine::
-bit 1 - if set insert udp checksum offload
+ testpmd> csum parse-tunnel (on|off) (tx_port_id)
-bit 2 - if set insert tcp checksum offload
+If enabled, the csum forward engine will try to recognize supported
+tunnel headers (vxlan, gre, ipip).
-bit 3 - if set insert sctp checksum offload
+If disabled, treat tunnel packets as non-tunneled packets (a inner
+header is handled as a packet payload).
.. note::
- Check the NIC Datasheet for hardware limits.
+ The port argument is the TX port like in the ``csum set`` command.
+Example:
-set fwd
+Consider a packet in packet like the following::
+
+ eth_out/ipv4_out/udp_out/vxlan/eth_in/ipv4_in/tcp_in
+
+* If parse-tunnel is enabled, the ``ip|udp|tcp|sctp`` parameters of ``csum set``
+ command relate to the inner headers (here ``ipv4_in`` and ``tcp_in``), and the
+ ``outer-ip parameter`` relates to the outer headers (here ``ipv4_out``).
+
+* If parse-tunnel is disabled, the ``ip|udp|tcp|sctp`` parameters of ``csum set``
+ command relate to the outer headers, here ``ipv4_out`` and ``udp_out``.

+~~~~~~~~
+
+Display the status of TCP Segmentation Offload::
-* io: forwards packets "as-is" in I/O mode.
- This is the fastest possible forwarding operation as it does not access packets data.
- This is the default mode.
+ testpmd> tso show (port_id)
-* mac: changes the source and the destination Ethernet addresses of packets before forwarding them.
+set port - gro
+~~~~~~~~~~~~~~
-* mac_retry: same as "mac" forwarding mode, but includes retries if the destination queue is full.
+Enable or disable GRO in ``csum`` forwarding engine::
-* macswap: MAC swap forwarding mode.
- Swaps the source and the destination Ethernet addresses of packets before forwarding them.
+ testpmd> set port <port_id> gro on|off
-* flowgen: multi-flow generation mode.
- Originates a bunch of flows (varying destination IP addresses), and terminate receive traffic.
+If enabled, the csum forwarding engine will perform GRO on the TCP/IPv4
+packets received from the given port.
-* rxonly: receives packets but doesn't transmit them.
+If disabled, packets received from the given port won't be performed
+GRO. By default, GRO is disabled for all ports.
-* txonly: generates and transmits packets without receiving any.
+.. note::
-* csum: changes the checksum field with HW or SW methods depending on the offload flags on the packet.
+ When enable GRO for a port, TCP/IPv4 packets received from the port
+ will be performed GRO. After GRO, all merged packets have bad
+ checksums, since the GRO library doesn't re-calculate checksums for
+ the merged packets. Therefore, if users want the merged packets to
+ have correct checksums, please select HW IP checksum calculation and
+ HW TCP checksum calculation for the port which the merged packets are
+ transmitted to.
-* icmpecho: receives a burst of packets, lookup for IMCP echo requests and, if any, send back ICMP echo replies.
+show port - gro
+~~~~~~~~~~~~~~~
+Display GRO configuration for a given port::
-Example:
+ testpmd> show port <port_id> gro
-.. code-block:: console
+set gro flush
+~~~~~~~~~~~~~
- testpmd> set fwd rxonly
+Set the cycle to flush the GROed packets from reassembly tables::
- Set rxonly packet forwarding mode
+ testpmd> set gro flush <cycles>
+
+When enable GRO, the csum forwarding engine performs GRO on received
+packets, and the GROed packets are stored in reassembly tables. Users
+can use this command to determine when the GROed packets are flushed
+from the reassembly tables.
+
+The ``cycles`` is measured in GRO operation times. The csum forwarding
+engine flushes the GROed packets from the tables every ``cycles`` GRO
+operations.
+
+By default, the value of ``cycles`` is 1, which means flush GROed packets
+from the reassembly tables as soon as one GRO operation finishes. The value
+of ``cycles`` should be in the range of 1 to ``GRO_MAX_FLUSH_CYCLES``.
+
+Please note that the large value of ``cycles`` may cause the poor TCP/IP
+stack performance. Because the GROed packets are delayed to arrive the
+stack, thus causing more duplicated ACKs and TCP retransmissions.

+.. note::
+
+ Port configuration changes only become active when forwarding is started/restarted.
+
+port attach
+~~~~~~~~~~~
+
+Attach a port specified by pci address or virtual device args::
+
+ testpmd> port attach (identifier)
+
+To attach a new pci device, the device should be recognized by kernel first.
+Then it should be moved under DPDK management.
+Finally the port can be attached to testpmd.
+
+For example, to move a pci device using ixgbe under DPDK management:
+
+.. code-block:: console
+
+ # Check the status of the available devices.
+ ./usertools/dpdk-devbind.py --status
+
+ Network devices using DPDK-compatible driver
+ ============================================
+ <none>
+
+ Network devices using kernel driver
+ ===================================
+ 0000:0a:00.0 '82599ES 10-Gigabit' if=eth2 drv=ixgbe unused=
+
+
+ # Bind the device to igb_uio.
+ sudo ./usertools/dpdk-devbind.py -b igb_uio 0000:0a:00.0
+
+
+ # Recheck the status of the devices.
+ ./usertools/dpdk-devbind.py --status
+ Network devices using DPDK-compatible driver
+ ============================================
+ 0000:0a:00.0 '82599ES 10-Gigabit' drv=igb_uio unused=
+
+To attach a port created by virtual device, above steps are not needed.
+
+For example, to attach a port whose pci address is 0000:0a:00.0.
+
+.. code-block:: console
+
+ testpmd> port attach 0000:0a:00.0
+ Attaching a new port...
+ EAL: PCI device 0000:0a:00.0 on NUMA socket -1
+ EAL: probe driver: 8086:10fb rte_ixgbe_pmd
+ EAL: PCI memory mapped at 0x7f83bfa00000
+ EAL: PCI memory mapped at 0x7f83bfa80000
+ PMD: eth_ixgbe_dev_init(): MAC: 2, PHY: 18, SFP+: 5
+ PMD: eth_ixgbe_dev_init(): port 0 vendorID=0x8086 deviceID=0x10fb
+ Port 0 is attached. Now total ports is 1
+ Done
+
+For example, to attach a port created by pcap PMD.
+
+.. code-block:: console
+
+ testpmd> port attach net_pcap0
+ Attaching a new port...
+ PMD: Initializing pmd_pcap for net_pcap0
+ PMD: Creating pcap-backed ethdev on numa socket 0
+ Port 0 is attached. Now total ports is 1
+ Done
+
+In this case, identifier is ``net_pcap0``.
+This identifier format is the same as ``--vdev`` format of DPDK applications.
+
+For example, to re-attach a bonded port which has been previously detached,
+the mode and slave parameters must be given.
+

+flow_director_filter
+~~~~~~~~~~~~~~~~~~~~
-Example:
+The Flow Director works in receive mode to identify specific flows or sets of flows and route them to specific queues.
-.. code-block:: console
+Four types of filtering are supported which are referred to as Perfect Match, Signature, Perfect-mac-vlan and
+Perfect-tunnel filters, the match mode is set by the ``--pkt-filter-mode`` command-line parameter:
+
+* Perfect match filters.
+ The hardware checks a match between the masked fields of the received packets and the programmed filters.
+ The masked fields are for IP flow.
+
+* Signature filters.
+ The hardware checks a match between a hash-based signature of the masked fields of the received packet.
+
+* Perfect-mac-vlan match filters.
+ The hardware checks a match between the masked fields of the received packets and the programmed filters.
+ The masked fields are for MAC VLAN flow.
+
+* Perfect-tunnel match filters.
+ The hardware checks a match between the masked fields of the received packets and the programmed filters.
+ The masked fields are for tunnel flow.
+
+The Flow Director filters can match the different fields for different type of packet: flow type, specific input set
+per flow type and the flexible payload.
+
+The Flow Director can also mask out parts of all of these fields so that filters
+are only applied to certain fields or parts of the fields.
+
+Different NICs may have different capabilities, command show port fdir (port_id) can be used to acquire the information.

-Set the speed and duplex mode for all ports or a specific port:
+Flow rules management
+---------------------
-port config (port_id|all) speed (10|100|1000|10000|auto) duplex (half|full|auto)
+Control of the generic flow API (*rte_flow*) is fully exposed through the
+``flow`` command (validation, creation, destruction, queries and operation
+modes).
-port config - queues/descriptors
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+Considering *rte_flow* overlaps with all `Filter Functions`_, using both
+features simultaneously may cause undefined side-effects and is therefore
+not recommended.
-Set number of queues/descriptors for rxq, txq, rxd and txd:
+``flow`` syntax
+~~~~~~~~~~~~~~~
-port config all (rxq|txq|rxd|txd) (value)
+Because the ``flow`` command uses dynamic tokens to handle the large number
+of possible flow rules combinations, its behavior differs slightly from
+other commands, in particular:
-This is equivalent to the --rxq, --txq, --rxd and --txd command-line options.
+- Pressing *?* or the *<tab>* key displays contextual help for the current
+ token, not that of the entire command.
-port config - max-pkt-len
-~~~~~~~~~~~~~~~~~~~~~~~~~
+- Optional and repeated parameters are supported (provided they are listed
+ in the contextual help).
-Set the maximum packet length:
+The first parameter stands for the operation mode. Possible operations and
+their general syntax are described below. They are covered in detail in the
+following sections.
-port config all max-pkt-len (value)
+- Check whether a flow rule can be created::
-This is equivalent to the --max-pkt-len command-line option.
+ flow validate {port_id}
+ [group {group_id}] [priority {level}] [ingress] [egress]
+ pattern {item} [/ {item} [...]] / end
+ actions {action} [/ {action} [...]] / end
-port config - CRC Strip
-~~~~~~~~~~~~~~~~~~~~~~~
+- Create a flow rule::
-Set hardware CRC stripping on or off for all ports:
+ flow create {port_id}
+ [group {group_id}] [priority {level}] [ingress] [egress]
+ pattern {item} [/ {item} [...]] / end
+ actions {action} [/ {action} [...]] / end
-port config all crc-strip (on|off)
+- Destroy specific flow rules::
-CRC stripping is off by default.
+ flow destroy {port_id} rule {rule_id} [...]
-The on option is equivalent to the --crc-strip command-line option.
+- Destroy all flow rules::
-port config - RX Checksum
-~~~~~~~~~~~~~~~~~~~~~~~~~
+ flow flush {port_id}
-Set hardware RX checksum offload to on or off for all ports:
+- Query an existing flow rule::
-port config all rx-cksum (on|off)
+ flow query {port_id} {rule_id} {action}
-Checksum offload is off by default.
+- List existing flow rules sorted by priority, filtered by group
+ identifiers::
-The on option is equivalent to the --enable-rx-cksum command-line option.
+ flow list {port_id} [group {group_id}] [...]
-port config - VLAN
-~~~~~~~~~~~~~~~~~~
+- Restrict ingress traffic to the defined flow rules::
-Set hardware VLAN on or off for all ports:
+ flow isolate {port_id} {boolean}
-port config all hw-vlan (on|off)
+Validating flow rules
+~~~~~~~~~~~~~~~~~~~~~
-Hardware VLAN is on by default.
+``flow validate`` reports whether a flow rule would be accepted by the
+underlying device in its current state but stops short of creating it. It is
+bound to ``rte_flow_validate()``::
-The off option is equivalent to the --disable-hw-vlan command-line option.
+ flow validate {port_id}
+ [group {group_id}] [priority {level}] [ingress] [egress]
+ pattern {item} [/ {item} [...]] / end
+ actions {action} [/ {action} [...]] / end
-port config - Drop Packets
-~~~~~~~~~~~~~~~~~~~~~~~~~~
+If successful, it will show::
-Set packet drop for packets with no descriptors on or off for all ports:
+ Flow rule validated
-port config all drop-en (on|off)
+Otherwise it will show an error message of the form::
-Packet dropping for packets with no descriptors is off by default.
+ Caught error type [...] ([...]): [...]
-The on option is equivalent to the --enable-drop-en command-line option.
+This command uses the same parameters as ``flow create``, their format is
+described in `Creating flow rules`_.
-port config - RSS
-~~~~~~~~~~~~~~~~~
+Check whether redirecting any Ethernet packet received on port 0 to RX queue
+index 6 is supported::
-Set the RSS (Receive Side Scaling) mode on or off:
+ testpmd> flow validate 0 ingress pattern eth / end
+ actions queue index 6 / end
+ Flow rule validated
+ testpmd>
-port config all rss (ip|udp|none)
+Port 0 does not support TCPv6 rules::
-RSS is on by default.
+ testpmd> flow validate 0 ingress pattern eth / ipv6 / tcp / end
+ actions drop / end
+ Caught error type 9 (specific pattern item): Invalid argument
+ testpmd>
-The off option is equivalent to the --disable-rss command-line option.
+Creating flow rules
+~~~~~~~~~~~~~~~~~~~
-port config - RSS Reta
-~~~~~~~~~~~~~~~~~~~~~~
+``flow create`` validates and creates the specified flow rule. It is bound
+to ``rte_flow_create()``::
-Set the RSS (Receive Side Scaling) redirection table:
+ flow create {port_id}
+ [group {group_id}] [priority {level}] [ingress] [egress]
+ pattern {item} [/ {item} [...]] / end
+ actions {action} [/ {action} [...]] / end
-port config all rss reta (hash,queue)[,(hash,queue)]
+If successful, it will return a flow rule ID usable with other commands::
-port config - DCB
-~~~~~~~~~~~~~~~~~
+ Flow rule #[...] created
-Set the DCB mode for an individual port:
+Otherwise it will show an error message of the form::
-port config (port_id) dcb vt (on|off) (traffic_class) pfc (on|off)
+ Caught error type [...] ([...]): [...]
-The traffic class should be 4 or 8.
+Parameters describe in the following order:
-port config - Burst
-~~~~~~~~~~~~~~~~~~~
+- Attributes (*group*, *priority*, *ingress*, *egress* tokens).
+- A matching pattern, starting with the *pattern* token and terminated by an
+ *end* pattern item.
+- Actions, starting with the *actions* token and terminated by an *end*
+ action.
-Set the number of packets per burst:
+These translate directly to *rte_flow* objects provided as-is to the
+underlying functions.
-port config all burst (value)
+The shortest valid definition only comprises mandatory tokens::
-This is equivalent to the --burst command-line option.
+ testpmd> flow create 0 pattern end actions end
-port config - Threshold
-~~~~~~~~~~~~~~~~~~~~~~~
+Note that PMDs may refuse rules that essentially do nothing such as this
+one.
-Set thresholds for TX/RX queues:
+**All unspecified object values are automatically initialized to 0.**
-port config all (threshold) (value)
+Attributes
+^^^^^^^^^^
-Where the threshold type can be:
+These tokens affect flow rule attributes (``struct rte_flow_attr``) and are
+specified before the ``pattern`` token.
-* txpt: Set the prefetch threshold register of the TX rings, 0 <= value <= 255.
+- ``group {group id}``: priority group.
+- ``priority {level}``: priority level within group.
+- ``ingress``: rule applies to ingress traffic.
+- ``egress``: rule applies to egress traffic.
-* txht: Set the host threshold register of the TX rings, 0 <= value <= 255.
+Each instance of an attribute specified several times overrides the previous
+value as shown below (group 4 is used)::
-* txwt: Set the write-back threshold register of the TX rings, 0 <= value <= 255.
+ testpmd> flow create 0 group 42 group 24 group 4 [...]
-* rxpt: Set the prefetch threshold register of the RX rings, 0 <= value <= 255.
+Note that once enabled, ``ingress`` and ``egress`` cannot be disabled.
-* rxht: Set the host threshold register of the RX rings, 0 <= value <= 255.
+While not specifying a direction is an error, some rules may allow both
+simultaneously.
-* rxwt: Set the write-back threshold register of the RX rings, 0 <= value <= 255.
+Most rules affect RX therefore contain the ``ingress`` token::
-* txfreet: Set the transmit free threshold of the TX rings, 0 <= value <= txd.
+ testpmd> flow create 0 ingress pattern [...]
-* rxfreet: Set the transmit free threshold of the RX rings, 0 <= value <= rxd.
+Matching pattern
+^^^^^^^^^^^^^^^^
-* txrst: Set the transmit RS bit threshold of TX rings, 0 <= value <= txd.
- These threshold options are also available from the command-line.
+A matching pattern starts after the ``pattern`` token. It is made of pattern
+items and is terminated by a mandatory ``end`` item.
-Flow Director Functions
------------------------
+Items are named after their type (*RTE_FLOW_ITEM_TYPE_* from ``enum
+rte_flow_item_type``).
-The Flow Director works in receive mode to identify specific flows or sets of flows and route them to specific queues.
+The ``/`` token is used as a separator between pattern items as shown
+below::
-Two types of filtering are supported which are referred to as Perfect Match and Signature filters:
+ testpmd> flow create 0 ingress pattern eth / ipv4 / udp / end [...]
-* Perfect match filters.
- The hardware checks a match between the masked fields of the received packets and the programmed filters.
+Note that protocol items like these must be stacked from lowest to highest
+layer to make sense. For instance, the following rule is either invalid or
+unlikely to match any packet::
-* Signature filters.
- The hardware checks a match between a hash-based signature of the masked fields of the received packet.
+ testpmd> flow create 0 ingress pattern eth / udp / ipv4 / end [...]
-The Flow Director filters can match the following fields in a packet:
+More information on these restrictions can be found in the *rte_flow*
+documentation.
-* Source IP and destination IP addresses.
+Several items support additional specification structures, for example
+``ipv4`` allows specifying source and destination addresses as follows::
-* Source port and destination port numbers (for UDP and TCP packets).
+ testpmd> flow create 0 ingress pattern eth / ipv4 src is 10.1.1.1
+ dst is 10.2.0.0 / end [...]
-* IPv4/IPv6 and UDP/ TCP/SCTP protocol match.
+This rule matches all IPv4 traffic with the specified properties.
-* VLAN header.
+In this example, ``src`` and ``dst`` are field names of the underlying
+``struct rte_flow_item_ipv4`` object. All item properties can be specified
+in a similar fashion.
-* Flexible 2-byte tuple match anywhere in the first 64 bytes of the packet.
+The ``is`` token means that the subsequent value must be matched exactly,
+and assigns ``spec`` and ``mask`` fields in ``struct rte_flow_item``
+accordingly. Possible assignment tokens are:
-The Flow Director can also mask out parts of all of these fields so that filters are only applied to certain fields
-or parts of the fields.
-For example it is possible to mask out sub-nets of IP addresses or to ignore VLAN headers.
+- ``is``: match value perfectly (with full bit-mask).
+- ``spec``: match value according to configured bit-mask.
+- ``last``: specify upper bound to establish a range.
+- ``mask``: specify bit-mask with relevant bits set to one.
+- ``prefix``: generate bit-mask from a prefix length.
-In the following sections, several common parameters are used in the Flow Director filters.
-These are explained below:
+These yield identical results::
-* src: A pair of source address values. The source IP, in IPv4 or IPv6 format, and the source port:
+ ipv4 src is 10.1.1.1
- src 192.168.0.1 1024
+::
- src 2001:DB8:85A3:0:0:8A2E:370:7000 1024
+ ipv4 src spec 10.1.1.1 src mask 255.255.255.255
-* dst: A pair of destination address values. The destination IP, in IPv4 or IPv6 format, and the destination port.
+::
-* flexbytes: A 2-byte tuple to be matched within the first 64 bytes of a packet.
+ ipv4 src spec 10.1.1.1 src prefix 32
-The offset where the match occurs is set by the --pkt-filter-flexbytes-offset command-line parameter
-and is counted from the first byte of the destination Ethernet MAC address.
-The default offset is 0xC bytes, which is the "Type" word in the MAC header.
-Typically, the flexbyte value is set to 0x0800 to match the IPv4 MAC type or 0x86DD to match IPv6.
-These values change when a VLAN tag is added.
+::
-* vlan: The VLAN header to match in the packet.
+ ipv4 src is 10.1.1.1 src last 10.1.1.1 # range with a single value
-* queue: The index of the RX queue to route matched packets to.
+::
-* soft: The 16-bit value in the MBUF flow director ID field for RX packets matching the filter.
+ ipv4 src is 10.1.1.1 src last 0 # 0 disables range
-add_signature_filter

- src (src_ip_address) (src_port)
+Properties can be modified multiple times::

-Link Bonding Functions
-----------------------
+As defined by *rte_flow*, the list is not ordered, all actions of a given
+rule are performed simultaneously. These are equivalent::
-The Link Bonding functions make it possible to dynamically create and
-manage link bonding devices from within testpmd interactive prompt.
+ queue index 6 / void / mark id 42 / end
-create bonded device
-~~~~~~~~~~~~~~~~~~~~
+::
-Create a new bonding device:
+ void / mark id 42 / queue index 6 / end
-create bonded device (mode) (socket)
+All actions in a list should have different types, otherwise only the last
+action of a given type is taken into account::
-For example, to create a bonded device in mode 1 on socket 0.
+ queue index 4 / queue index 5 / queue index 6 / end # will use queue 6
-.. code-block:: console
+::
- testpmd> create bonded 1 0
- created new bonded device (port X)
+ drop / drop / drop / end # drop is performed only once
-add bonding slave
-~~~~~~~~~~~~~~~~~
+::
-Adds Ethernet device to a Link Bonding device:
+ mark id 42 / queue index 3 / mark id 24 / end # mark will be 24
-add bonding slave (slave id) (port id)
+Considering they are performed simultaneously, opposite and overlapping
+actions can sometimes be combined when the end result is unambiguous::
-For example, to add Ethernet device (port 6) to a Link Bonding device (port 10).
+ drop / queue index 6 / end # drop has no effect
-.. code-block:: console
+::
- testpmd> add bonding slave 6 10
+ drop / dup index 6 / end # same as above
+::
-remove bonding slave
-~~~~~~~~~~~~~~~~~~~~
+ queue index 6 / rss queues 6 7 8 / end # queue has no effect
-Removes an Ethernet slave device from a Link Bonding device:
+::
-remove bonding slave (slave id) (port id)
+ drop / passthru / end # drop has no effect
-For example, to remove Ethernet slave device (port 6) to a Link Bonding device (port 10).
+Note that PMDs may still refuse such combinations.
-.. code-block:: console
+Actions
+^^^^^^^
- testpmd> remove bonding slave 6 10
+This section lists supported actions and their attributes, if any.
-set bonding mode
-~~~~~~~~~~~~~~~~
+- ``end``: end list of actions.
-Set the Link Bonding mode of a Link Bonding device:
+- ``void``: no-op action.
-set bonding mode (value) (port id)
+- ``passthru``: let subsequent rule process matched packets.
-For example, to set the bonding mode of a Link Bonding device (port 10) to broadcast (mode 3).
+- ``mark``: attach 32 bit value to packets.
-.. code-block:: console
+ - ``id {unsigned}``: 32 bit value to return with packets.
- testpmd> set bonding mode 3 10
+- ``flag``: flag packets.
-set bonding primary
-~~~~~~~~~~~~~~~~~~~
+- ``queue``: assign packets to a given queue index.
-Set an Ethernet slave device as the primary device on a Link Bonding device:
+ - ``index {unsigned}``: queue index to use.
-set bonding primary (slave id) (port id)
+- ``drop``: drop packets (note: passthru has priority).
-For example, to set the Ethernet slave device (port 6) as the primary port of a Link Bonding device (port 10).
+- ``count``: enable counters for this rule.
-.. code-block:: console
+- ``dup``: duplicate packets to a given queue index.
- testpmd> set bonding primary 6 10
+ - ``index {unsigned}``: queue index to duplicate packets to.
-set bonding mac
-~~~~~~~~~~~~~~~
+- ``rss``: spread packets among several queues.
-Set the MAC address of a Link Bonding device:
+ - ``queues [{unsigned} [...]] end``: queue indices to use.
-set bonding mac (port id) (mac)
+- ``pf``: redirect packets to physical device function.
-For example, to set the MAC address of a Link Bonding device (port 10) to 00:00:00:00:00:01
+- ``vf``: redirect packets to virtual device function.
-.. code-block:: console
+ - ``original {boolean}``: use original VF ID if possible.
+ - ``id {unsigned}``: VF ID to redirect packets to.
- testpmd> set bonding mac 10 00:00:00:00:00:01
+Destroying flow rules
+~~~~~~~~~~~~~~~~~~~~~
-set bonding xmit_balance_policy
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+``flow destroy`` destroys one or more rules from their rule ID (as returned
+by ``flow create``), this command calls ``rte_flow_destroy()`` as many
+times as necessary::
-Set the transmission policy for a Link Bonding device when it is in Balance XOR mode:
+ flow destroy {port_id} rule {rule_id} [...]
-set bonding xmit_balance_policy (port_id) (l2|l23|l34)
+If successful, it will show::
-For example, set a Link Bonding device (port 10) to use a balance policy of layer 3+4 (IP addresses & UDP ports )
+ Flow rule #[...] destroyed
-.. code-block:: console
+It does not report anything for rule IDs that do not exist. The usual error
+message is shown when a rule cannot be destroyed::
- testpmd> set bonding xmit_balance_policy 10 l34
+ Caught error type [...] ([...]): [...]
+``flow flush`` destroys all rules on a device and does not take extra
+arguments. It is bound to ``rte_flow_flush()``::
-set bonding mon_period
-~~~~~~~~~~~~~~~~~~~~~~
+ flow flush {port_id}
-Set the link status monitoring polling period in milliseconds for a bonding devicie.
+Any errors are reported as above.
-This adds support for PMD slave devices which do not support link status interrupts.
-When the mon_period is set to a value greater than 0 then all PMD's which do not support
-link status ISR will be queried every polling interval to check if their link status has changed.
+Creating several rules and destroying them::
-set bonding mon_period (port_id) (value)
+ testpmd> flow create 0 ingress pattern eth / ipv6 / end
+ actions queue index 2 / end
+ Flow rule #0 created
+ testpmd> flow create 0 ingress pattern eth / ipv4 / end
+ actions queue index 3 / end
+ Flow rule #1 created
+ testpmd> flow destroy 0 rule 0 rule 1
+ Flow rule #1 destroyed
+ Flow rule #0 destroyed
+ testpmd>
-For example, to set the link status monitoring polling period of bonded device (port 5) to 150ms
+The same result can be achieved using ``flow flush``::
-.. code-block:: console
+ testpmd> flow create 0 ingress pattern eth / ipv6 / end
+ actions queue index 2 / end
+ Flow rule #0 created
+ testpmd> flow create 0 ingress pattern eth / ipv4 / end
+ actions queue index 3 / end
+ Flow rule #1 created
+ testpmd> flow flush 0
+ testpmd>
- testpmd> set bonding mon_period 5 150
+Non-existent rule IDs are ignored::
+ testpmd> flow create 0 ingress pattern eth / ipv6 / end
+ actions queue index 2 / end
+ Flow rule #0 created
+ testpmd> flow create 0 ingress pattern eth / ipv4 / end
+ actions queue index 3 / end
+ Flow rule #1 created
+ testpmd> flow destroy 0 rule 42 rule 10 rule 2
+ testpmd>
+ testpmd> flow destroy 0 rule 0
+ Flow rule #0 destroyed
+ testpmd>
-show bonding config
+Querying flow rules
~~~~~~~~~~~~~~~~~~~
-Show the current configuration of a Link Bonding device:
+``flow query`` queries a specific action of a flow rule having that
+ability. Such actions collect information that can be reported using this
+command. It is bound to ``rte_flow_query()``::
-show bonding config (port id)
+ flow query {port_id} {rule_id} {action}
-For example,
-to show the configuration a Link Bonding device (port 9) with 3 slave devices (1, 3, 4)
-in balance mode with a transmission policy of layer 2+3.
+If successful, it will display either the retrieved data for known actions
+or the following message::
-.. code-block:: console
+ Cannot display result for action type [...] ([...])
- testpmd> show bonding config 9
- Bonding mode: 2
- Balance Xmit Policy: BALANCE_XMIT_POLICY_LAYER23
- Slaves (3): [1 3 4]
- Active Slaves (3): [1 3 4]
- Primary: [3]
+Otherwise, it will complain either that the rule does not exist or that some
+error occurred::
-Register Functions
-------------------
+ Flow rule #[...] not found
-The Register functions can be used to read from and write to registers on the network card referenced by a port number.
-This is mainly useful for debugging purposes.
-Reference should be made to the appropriate datasheet for the network card for details on the register addresses
-and fields that can be accessed.
+::
-read reg
-~~~~~~~~
+ Caught error type [...] ([...]): [...]
-Display the value of a port register:
+Currently only the ``count`` action is supported. This action reports the
+number of packets that hit the flow rule and the total number of bytes. Its
+output has the following format::
-read reg (port_id) (address)
+ count:
+ hits_set: [...] # whether "hits" contains a valid value
+ bytes_set: [...] # whether "bytes" contains a valid value
+ hits: [...] # number of packets
+ bytes: [...] # number of bytes
-For example, to examine the Flow Director control register (FDIRCTL, 0x0000EE000) on an Intel® 82599 10 GbE Controller:
+Querying counters for TCPv6 packets redirected to queue 6::
-.. code-block:: console
+ testpmd> flow create 0 ingress pattern eth / ipv6 / tcp / end
+ actions queue index 6 / count / end
+ Flow rule #4 created
+ testpmd> flow query 0 4 count
+ count:
+ hits_set: 1
+ bytes_set: 0
+ hits: 386446
+ bytes: 0

- testpmd> read reg 0 0xEE00
- port 0 PCI register at offset 0xEE00: 0x4A060029 (1241907241)
+Listing flow rules
+~~~~~~~~~~~~~~~~~~
-read regfield
-~~~~~~~~~~~~~
+``flow list`` lists existing flow rules sorted by priority and optionally
+filtered by group identifiers::
+
+ flow list {port_id} [group {group_id}] [...]
+
+This command only fails with the following message if the device does not
+exist::
+
+ Invalid port [...]
+
+Output consists of a header line followed by a short description of each
+flow rule, one per line. There is no output at all when no flow rules are
+configured on the device::
+
+ ID Group Prio Attr Rule
+ [...] [...] [...] [...] [...]
+
+``Attr`` column flags:
+
+- ``i`` for ``ingress``.
+- ``e`` for ``egress``.
+
+Creating several flow rules and listing them::

+
+Toggling isolated mode
+~~~~~~~~~~~~~~~~~~~~~~
-Display a port register bit field:
+``flow isolate`` can be used to tell the underlying PMD that ingress traffic
+must only be injected from the defined flow rules; that no default traffic
+is expected outside those rules and the driver is free to assign more
+resources to handle them. It is bound to ``rte_flow_isolate()``::
-read regfield (port_id) (address) (bit_x) (bit_y)
+ flow isolate {port_id} {boolean}
-For example, reading the lowest two bits from the register in the example above:
+If successful, enabling or disabling isolated mode shows either::

-.. code-block:: console
+Enabling isolated mode::
- testpmd> read regbit 0 0xEE00 0
- port 0 PCI register at offset 0xEE00: bit 0=1
+ testpmd> flow isolate 0 true
+ Ingress traffic on port 0 is now restricted to the defined flow rules

-write reg
-~~~~~~~~~
+Disabling isolated mode::
-Set the value of a port register:
+ testpmd> flow isolate 0 false
+ Ingress traffic on port 0 is not restricted anymore to the defined flow rules
+ testpmd>
-write reg (port_id) (address) (value)
+Sample QinQ flow rules
+~~~~~~~~~~~~~~~~~~~~~~
-For example, to clear a register:
+Before creating QinQ rule(s) the following commands should be issued to enable QinQ::
-.. code-block:: console
+ testpmd> port stop 0
+ testpmd> vlan set qinq on 0
- testpmd> write reg 0 0xEE00 0x0
- port 0 PCI register at offset 0xEE00: 0x00000000 (0)
+The above command sets the inner and outer TPID's to 0x8100.
-write regfield
-~~~~~~~~~~~~~~
+To change the TPID's the following commands should be used::
-Set bit field of a port register:
+ testpmd> vlan set outer tpid 0xa100 0
+ testpmd> vlan set inner tpid 0x9100 0
+ testpmd> port start 0
-write regfield (port_id) (address) (bit_x) (bit_y) (value)
+Validate and create a QinQ rule on port 0 to steer traffic to a VF queue in a VM.
-For example, writing to the register cleared in the example above:
+::
-.. code-block:: console
+ testpmd> flow validate 0 ingress pattern eth / vlan tci is 123 /
+ vlan tci is 456 / end actions vf id 1 / queue index 0 / end
+ Flow rule #0 validated
- testpmd> write regfield 0 0xEE00 0 1 2
- port 0 PCI register at offset 0xEE00: 0x00000002 (2)
+ testpmd> flow create 0 ingress pattern eth / vlan tci is 4 /
+ vlan tci is 456 / end actions vf id 123 / queue index 0 / end
+ Flow rule #0 created
-write regbit
-~~~~~~~~~~~~
+ testpmd> flow list 0
+ ID Group Prio Attr Rule
+ 0 0 0 i- ETH VLAN VLAN=>VF QUEUE
-Set single bit value of a port register:
+Validate and create a QinQ rule on port 0 to steer traffic to a queue on the host.
-write regbit (port_id) (address) (bit_x) (value)
+::
-For example, to set the high bit in the register from the example above:
+ testpmd> flow validate 0 ingress pattern eth / vlan tci is 321 /
+ vlan tci is 654 / end actions pf / queue index 0 / end
+ Flow rule #1 validated
-.. code-block:: console
+ testpmd> flow create 0 ingress pattern eth / vlan tci is 321 /
