Function Documentation

   int rte_pmd_dpaa2_mux_flow_create (uint32_t dpdmux_id, struct rte_flow_item pattern[], struct rte_flow_action
       actions[])
       Create a flow rule to demultiplex ethernet traffic to separate network interfaces.

       Parameters
           dpdmux_id ID of the DPDMUX MC object.
           pattern Pattern specification.
           actions Associated actions.

       Returns
           0 in case of success, otherwise failure.

   __rte_experimental void rte_pmd_dpaa2_mux_dump_counter (FILE * f, uint32_t dpdmux_id, int num_if)
       Warning
           EXPERIMENTAL: this API may change, or be removed, without prior notice

       Dump demultiplex ethernet traffic counters

       Parameters
           f output stream
           dpdmux_id ID of the DPDMUX MC object.
           num_if number of interface in dpdmux object

   __rte_experimental int rte_pmd_dpaa2_mux_rx_frame_len (uint32_t dpdmux_id, uint16_t max_rx_frame_len)
       Warning
           EXPERIMENTAL: this API may change, or be removed, without prior notice

       demultiplex interface max rx frame length configure

       Parameters
           dpdmux_id ID of the DPDMUX MC object.
           max_rx_frame_len maximum receive frame length (will be checked to be minimux of all dpnis)

   int rte_pmd_dpaa2_set_custom_hash (uint16_t port_id, uint16_t offset, uint8_t size)
       Create a custom hash key on basis of offset of start of packet and size. for e.g. if we need GRE packets
       (non-vlan and without any extra headers) to be hashed on basis of inner IP header, we will provide offset
       as: 14 (eth) + 20 (IP) + 4 (GRE) + 12 (Inner Src offset) = 50 and size as 8 bytes.

       Parameters
           port_id The port identifier of the Ethernet device.
           offset Offset from the start of packet which needs to be included to calculate hash
           size Size of the hash input key

       Returns

           • 0 if successful.

           • Negative in case of failure.

   __rte_experimental void rte_pmd_dpaa2_thread_init (void)
       Warning
           EXPERIMENTAL: this API may change, or be removed, without prior notice

       Do thread specific initialization

   __rte_experimental uint32_t rte_pmd_dpaa2_get_tlu_hash (uint8_t * key, int size)
       Warning
           EXPERIMENTAL: this API may change, or be removed, without prior notice

       Generate the DPAA2 WRIOP based hash value

       Parameters
           key Array of key data
           size Size of the hash input key in bytes

       Returns

           • 0 if successful.

           • Negative in case of failure.
