Function Documentation

rte_pmd_dpaa2_mux_flow_create()

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.
[in]	pattern	Pattern specification.
[in]	actions	Associated actions.

Returns

0 in case of success, otherwise failure.

rte_pmd_dpaa2_mux_dump_counter()

__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_pmd_dpaa2_mux_rx_frame_len()

__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)

rte_pmd_dpaa2_set_custom_hash()

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_pmd_dpaa2_thread_init()

__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_pmd_dpaa2_get_tlu_hash()

__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.
