Function Documentation

__rte_experimental struct rte_flow* rte_pmd_dpaa2_mux_flow_create	(	uint32_t	dpdmux_id,
		struct rte_flow_item *	pattern[],
		struct rte_flow_action *	actions[]
	)

Warning

EXPERIMENTAL: this API may change, or be removed, without prior notice

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

A valid handle in case of success, NULL otherwise.

__rte_experimental int rte_pmd_dpaa2_set_custom_hash	(	uint16_t	port_id,
		uint16_t	offset,
		uint8_t	size
	)

Warning

EXPERIMENTAL: this API may change, or be removed, without prior notice

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.
