Function Details

ocs_node_t* ocs_node_alloc	(	ocs_sport_t *	sport,
		uint32_t	port_id,
		uint8_t	init,
		uint8_t	targ
	)

Allocate an fc node structure and add to node list.

Parameters

sport	pointer to the SPORT from which this node is allocated
port_id	FC port ID of new node
init	Port is an inititiator (sent a plogi)
targ	Port is potentially a target

Returns: pointer to the object or NULL if none available

Definition at line 415 of file ocs_node.c.

int32_t ocs_node_create_pool	(	ocs_t *	ocs,
		uint32_t	node_count
	)

allocate node object pool

A pool of ocs_node_t objects is allocated.

Parameters

ocs	pointer to driver instance context
node_count	count of nodes to allocate

Returns: returns 0 for success, a negative error code value for failure.

Definition at line 281 of file ocs_node.c.

ocs_node_t* ocs_node_find	(	ocs_sport_t *	sport,
		uint32_t	port_id
	)

Find an FC node structure given the FC port ID.

Parameters

sport	the SPORT to search
port_id	FC port ID

Returns: pointer to the object or NULL if not found

Definition at line 202 of file ocs_node.c.

ocs_node_t* ocs_node_find_wwnn	(	ocs_sport_t *	sport,
		uint64_t	wwnn
	)

Find an FC node structure given the WWNN.

Parameters

sport	the SPORT to search
wwnn	the WWNN to search for (host endian)

Returns: pointer to the object or NULL if not found

Definition at line 250 of file ocs_node.c.

ocs_node_t* ocs_node_find_wwpn	(	ocs_sport_t *	sport,
		uint64_t	wwpn
	)

wwpn	the WWPN to search for (host endian)

Returns: pointer to the object or NULL if not found

Definition at line 223 of file ocs_node.c.

int32_t ocs_node_free ( ocs_node_t * node )

free a node structure

The node structure given by 'node' is free'd

Parameters

node	the node to free

Returns: returns 0 for success, a negative error code value for failure.

Definition at line 510 of file ocs_node.c.

void ocs_node_free_pool ( ocs_t * ocs )
