Function Documentation

struct rte_flow* 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

A valid handle in case of success, NULL otherwise.

__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.
