Enumeration Type Documentation

rte_pmd_cnxk_sec_action_alg

enum rte_pmd_cnxk_sec_action_alg

Algorithm type to be used with security action to calculate SA_index

Enumerator
RTE_PMD_CNXK_SEC_ACTION_ALG0	No swizzling of SPI bits into SA index. SA_index is from SA_XOR if enabled.
RTE_PMD_CNXK_SEC_ACTION_ALG1	SPI<31:28> has 4 upper bits which segment the sequence number space. Initial SA_index is from SA_XOR if enabled. SA_alg = { 4'b0, SA_mcam[27:0] + SPI[31:28]}
RTE_PMD_CNXK_SEC_ACTION_ALG2	SPI<27:25> segment the sequence number space. Initial SA_index is from SA_XOR if enabled. SA_alg = { 7'b0, SA_mcam[24:0] + SPI[27:25]}
RTE_PMD_CNXK_SEC_ACTION_ALG3	SPI<28:25> segment the sequence number space. Initial SA_index is from SA_XOR if enabled. SA_alg = { 7'b0, SA_mcam[24:0] + SPI[28:25]}
RTE_PMD_CNXK_SEC_ACTION_ALG4	The inbound SPI maybe "random", therefore we want the MCAM to be capable of remapping the SPI to an arbitrary SA_index. SPI to SA is done using a lookup in NIX/NPC cam entry with key as SPI, MATCH_ID, LFID.

Function Documentation

rte_pmd_cnxk_hw_sa_read()

__rte_experimental int rte_pmd_cnxk_hw_sa_read	(	void *	device,
		struct rte_security_session *	sess,
		void *	data,
		uint32_t	len
	)

Read HW SA context from session.

Parameters

	device	Port identifier of Ethernet device.
	sess	Handle of the security session.
[out]	data	Destination pointer to copy SA context for application.
	len	Length of SA context to copy into data parameter.

Returns

0 on success, a negative errno value otherwise.

rte_pmd_cnxk_hw_sa_write()

__rte_experimental int rte_pmd_cnxk_hw_sa_write	(	void *	device,
		struct rte_security_session *	sess,
		void *	data,
		uint32_t	len
	)

Write HW SA context to session.

Parameters

	device	Port identifier of Ethernet device.
	sess	Handle of the security session.
[in]	data	Source data pointer from application to copy SA context into session.
	len	Length of SA context to copy from data parameter.

Returns

0 on success, a negative errno value otherwise.

rte_pmd_cnxk_inl_ipsec_res()

__rte_experimental void* rte_pmd_cnxk_inl_ipsec_res

(

struct rte_mbuf *

mbuf

)

Get pointer to CPT result info for inline inbound processed pkt.

It is recommended to use this API only when mbuf indicates packet was processed with inline IPsec and there was a failure with the same i.e mbuf->ol_flags indicates (RTE_MBUF_F_RX_SEC_OFFLOAD | RTE_MBUF_F_RX_SEC_OFFLOAD_FAILED).

Parameters

mbuf	Pointer to packet that was just received and was processed with Inline IPsec.

Returns

• Pointer to mbuf location where CPT result info is stored on success.
• NULL on failure.
