Functions
int	lcore_pkt_proc_func (void *lcore_args)
	The entry point for each L-Core's main processing loop. Each L-Core polls a different Rx queue on the Host PF(s). If the packet indicates the need for a new tunnel to be established, it will be passed to the psp_svc object. Note multiple such packets may be received during the creation of the tunnel; in any case, they will be resubmitted to the encryption pipeline once the new flow has been created. More...

handle_arp()

uint16_t handle_arp	(	struct rte_mempool *	mpool,
		uint16_t	port_id,
		uint16_t	queue_id,
		rte_ether_addr *	port_src_mac,
		const struct rte_mbuf *	request_pkt,
		uint32_t	arp_response_meta_flag
	)

Used to reply to an ARP request.

@mpool [in]: the mempool to allocate the response packet from @port_id [in]: the port on which to send the ARP response @queue_id [in]: the queue on which to send the ARP response @port_src_mac [in]: the source mac address of the port @request_pkt [in]: the ARP request packet @arp_response_meta_flag [in]: the metadata flag to set on the ARP response

Returns

: number of ARP packets handled (currently only one packet is supported)

handle_neighbor_solicitation()

uint16_t handle_neighbor_solicitation	(	struct rte_mempool *	mpool,
		uint16_t	port_id,
		uint16_t	queue_id,
		rte_ether_addr *	port_src_mac,
		const struct rte_mbuf *	request_pkt,
		uint32_t	na_response_meta_flag
	)

Used to reply to a Neighbor Solicitation packet.

@mpool [in]: the mempool to allocate the response packet from @port_id [in]: the port on which to send the Neighbor Solicitation response @queue_id [in]: the queue on which to send the Neighbor Solicitation response @port_src_mac [in]: the source mac address of the port @request_pkt [in]: the Neighbor Solicitation packet @na_response_meta_flag [in]: the metadata flag to set on the Neighbor Solicitation response

Returns

: number of Neighbor Solicitation packets handled (currently only one packet is supported)

lcore_pkt_proc_func()

int lcore_pkt_proc_func

(

void *

lcore_args

)

The entry point for each L-Core's main processing loop. Each L-Core polls a different Rx queue on the Host PF(s). If the packet indicates the need for a new tunnel to be established, it will be passed to the psp_svc object. Note multiple such packets may be received during the creation of the tunnel; in any case, they will be resubmitted to the encryption pipeline once the new flow has been created.

@lcore_args [in]: a pointer to an lcore_params struct

Returns

: 0 on success (the main loop exited normally), negative value otherwise

reinject_packet()

bool reinject_packet	(	struct rte_mbuf *	packet,
		uint16_t	port_id
	)

Used by the psp_svc to re-inject a packet via the Host PF Tx queue after a new tunnel has been established.

@packet [in]: the packet to submit into the egress pipeline @port_id [in]: the port on which to send the packet, usually the host PF

Returns

: true if the packet was successfully sent, false if too many retries failed
