It is not currently possible to specify a specific source Ethernet address. 306 307* ``macswap``: MAC swap forwarding mode. 308 Swaps the source and the destination Ethernet addresses of packets before forwarding them. 309 310* ``flowgen``: Multi-flow generation mode. 311 Originates a number of flows (with varying destination IP addresses), and terminate receive traffic. 312 313* ``rxonly``: Receives packets but doesn't transmit them. 314 315* ``txonly``: Generates and transmits packets without receiving any. 316 317* ``csum``: Changes the checksum field with hardware or software methods depending on the offload flags on the packet. 318 319* ``icmpecho``: Receives a burst of packets, lookup for IMCP echo requests and, if any, send back ICMP echo replies. 320 321* ``ieee1588``: Demonstrate L2 IEEE1588 V2 PTP timestamping for RX and TX. Requires ``CONFIG_RTE_LIBRTE_IEEE1588=y``. 322 323* ``tm``: Traffic Management forwarding mode 324 Demonstrates the use of ethdev traffic management APIs and softnic PMD for 325 QoS traffic management. In this mode, 5-level hierarchical QoS scheduler is 326 available as an default option that can be enabled through CLI. The user can 327 also modify the default hierarchy or specify the new hierarchy through CLI for 328 implementing QoS scheduler.

By default, GRO is disabled for all ports. 961 962.. note:: 963 964 When enable GRO for a port, TCP/IPv4 packets received from the port 965 will be performed GRO. After GRO, all merged packets have bad 966 checksums, since the GRO library doesn't re-calculate checksums for 967 the merged packets. Therefore, if users want the merged packets to 968 have correct checksums, please select HW IP checksum calculation and 969 HW TCP checksum calculation for the port which the merged packets are 970 transmitted to. 971 972show port - gro 973~~~~~~~~~~~~~~~ 974 975Display GRO configuration for a given port:: 976 977 testpmd> show port <port_id> gro 978 979set gro flush 980~~~~~~~~~~~~~ 981 982Set the cycle to flush the GROed packets from reassembly tables:: 983 984 testpmd> set gro flush <cycles> 985 986When enable GRO, the csum forwarding engine performs GRO on received 987packets, and the GROed packets are stored in reassembly tables. Users 988can use this command to determine when the GROed packets are flushed 989from the reassembly tables. 990 991The ``cycles`` is measured in GRO operation times. The csum forwarding 992engine flushes the GROed packets from the tables every ``cycles`` GRO 993operations. 994 995By default, the value of ``cycles`` is 1, which means flush GROed packets 996from the reassembly tables as soon as one GRO operation finishes. The value 997of ``cycles`` should be in the range of 1 to ``GRO_MAX_FLUSH_CYCLES``. 998 999Please note that the large value of ``cycles`` may cause the poor TCP/IP 1000stack performance. Because the GROed packets are delayed to arrive the 1001stack, thus causing more duplicated ACKs and TCP retransmissions. 1002 1003set port - gso 1004~~~~~~~~~~~~~~ 1005 1006Toggle per-port GSO support in ``csum`` forwarding engine:: 1007 1008 testpmd> set port <port_id> gso on|off 1009 1010If enabled, the csum forwarding engine will perform GSO on supported IPv4 1011packets, transmitted on the given port. 1012 1013If disabled, packets transmitted on the given port will not undergo GSO. 1014By default, GSO is disabled for all ports. 1015 1016.. note:: 1017 1018 When GSO is enabled on a port, supported IPv4 packets transmitted on that 1019 port undergo GSO. Afterwards, the segmented packets are represented by 1020 multi-segment mbufs; however, the csum forwarding engine doesn't calculation 1021 of checksums for GSO'd segments in SW.

them to specific queues. 2688 2689Four types of filtering are supported which are referred to as Perfect Match, Signature, Perfect-mac-vlan and 2690Perfect-tunnel filters, the match mode is set by the ``--pkt-filter-mode`` command-line parameter: 2691 2692* Perfect match filters. 2693 The hardware checks a match between the masked fields of the received packets and the programmed filters. 2694 The masked fields are for IP flow. 2695 2696* Signature filters. 2697 The hardware checks a match between a hash-based signature of the masked fields of the received packet. 2698 2699* Perfect-mac-vlan match filters. 2700 The hardware checks a match between the masked fields of the received packets and the programmed filters. 2701 The masked fields are for MAC VLAN flow. 2702 2703* Perfect-tunnel match filters. 2704 The hardware checks a match between the masked fields of the received packets and the programmed filters. 2705 The masked fields are for tunnel flow. 2706 2707* Perfect-raw-flow-type match filters. 2708 The hardware checks a match between the masked fields of the received packets and pre-loaded raw (template) packet. 2709 The masked fields are specified by input sets. 2710 2711The Flow Director filters can match the different fields for different type of packet: flow type, specific input set 2712per flow type and the flexible payload. 2713 2714The Flow Director can also mask out parts of all of these fields so that filters 2715are only applied to certain fields or parts of the fields. 2716 2717Note that for raw flow type mode the source and destination fields in the 2718raw packet buffer need to be presented in a reversed order with respect 2719to the expected received packets. 2720For example: IP source and destination addresses or TCP/UDP/SCTP 2721source and destination ports 2722 2723Different NICs may have different capabilities, command show port fdir (port_id) can be used to acquire the information. 2724 2725# Commands to

Possible operations and 2969their general syntax are described below. They are covered in detail in the 2970following sections. 2971 2972- Check whether a flow rule can be created:: 2973 2974 flow validate {port_id} 2975 [group {group_id}] [priority {level}] [ingress] [egress] 2976 pattern {item} [/ {item} [...]] / end 2977 actions {action} [/ {action} [...]] / end 2978 2979- Create a flow rule:: 2980 2981 flow create {port_id} 2982 [group {group_id}] [priority {level}] [ingress] [egress] 2983 pattern {item} [/ {item} [...]] / end 2984 actions {action} [/ {action} [...]] / end 2985 2986- Destroy specific flow rules:: 2987 2988 flow destroy {port_id} rule {rule_id} [...] 2989 2990- Destroy all flow rules:: 2991 2992 flow flush {port_id} 2993 2994- Query an existing flow rule:: 2995 2996 flow query {port_id} {rule_id} {action} 2997 2998- List existing flow rules sorted by priority, filtered by group 2999 identifiers:: 3000 3001 flow list {port_id} [group {group_id}] [...] 3002 3003- Restrict ingress traffic to the defined flow rules:: 3004 3005 flow isolate {port_id} {boolean} 3006 3007Validating flow rules 3008~~~~~~~~~~~~~~~~~~~~~ 3009 3010``flow validate`` reports whether a flow rule would be accepted by the 3011underlying device in its current state but stops short of creating it.

All item properties can be specified 3142in a similar fashion. 3143 3144The ``is`` token means that the subsequent value must be matched exactly, 3145and assigns ``spec`` and ``mask`` fields in ``struct rte_flow_item`` 3146accordingly. Possible assignment tokens are: 3147 3148- ``is``: match value perfectly (with full bit-mask). 3149- ``spec``: match value according to configured bit-mask. 3150- ``last``: specify upper bound to establish a range. 3151- ``mask``: specify bit-mask with relevant bits set to one. 3152- ``prefix``: generate bit-mask from a prefix length. 3153 3154These yield identical results:: 3155 3156 ipv4 src is 10.1.1.1 3157 3158:: 3159 3160 ipv4 src spec 10.1.1.1 src mask 255.255.255.255 3161 3162:: 3163 3164 ipv4 src spec 10.1.1.1 src prefix 32 3165 3166:: 3167 3168 ipv4 src is 10.1.1.1 src last 10.1.1.1 # range with a single value 3169 3170:: 3171 3172 ipv4 src is 10.1.1.1 src last 0 # 0 disables range 3173 3174Inclusive ranges can be defined with ``last``:: 3175 3176 ipv4 src is 10.1.1.1 src last 10.2.3.4 # 10.1.1.1 to 10.2.3.4 3177 3178Note that ``mask`` affects both ``spec`` and ``last``:: 3179 3180 ipv4 src is 10.1.1.1 src last 10.2.3.4 src mask 255.255.0.0 3181 # matches 10.1.0.0 to 10.2.255.255 3182 3183Properties can be modified multiple times:: 3184 3185 ipv4 src is 10.1.1.1 src is 10.1.2.3 src is 10.2.3.4 # matches 10.2.3.4 3186 3187:: 3188 3189 ipv4 src is 10.1.1.1 src prefix 24 src prefix 16 # matches 10.1.0.0/16 3190 3191Pattern items 3192^^^^^^^^^^^^^ 3193 3194This section lists supported pattern items and their attributes, if any. 3195 3196- ``end``: end list of pattern items. 3197 3198- ``void``: no-op pattern item. 3199 3200- ``invert``: perform actions when pattern does not match. 3201 3202- ``any``: match any protocol for the current layer. 3203 3204 -
