Function Documentation

cnet_arp_alloc()

CNDP_API struct arp_entry* cnet_arp_alloc

(

void

)

Allocate an ARP entry

Returns

NULL on error, otherwise pointer to ARP entry.

cnet_arp_free()

CNDP_API void cnet_arp_free

(

struct arp_entry *

entry

)

Free an ARP entry

Parameters

entry

The ARP entry to free.

cnet_arp_create()

CNDP_API int cnet_arp_create	(	struct cnet *	_cnet,
		uint32_t	num_entries,
		uint32_t	num_tbl8s
	)

Create the ARP table and structure to hold ARP information.

Parameters

_cnet	The pointer to the current CNET structure.
num_entries	The number of entries to allocate in ARP table, if zero use ARP_FIB_DEFAULT_ENTRIES.
num_tbl8s	The number of table entries to allocate in ARP table, if zero use ARP_FIB_DEFAULT_NUM_TBLS8.

Returns

0 on success or -1 on error.

cnet_arp_destroy()

CNDP_API int cnet_arp_destroy

(

struct cnet *

cnet

)

Destroy the ARP table and structure to hold ARP information.

Parameters

cnet	The pointer to the current CNET structure.

Returns

0 on success or -1 on error.

cnet_arp_add()

CNDP_API struct arp_entry* cnet_arp_add	(	int	netif_idx,
		struct in_addr *	addr,
		struct ether_addr *	mac,
		int	perm
	)

Add an ARP entry to the ARP table. If perm is set then create a static entry.

Parameters

netif_idx	The netif structure index to assign the ARP entry.
addr	The IP address to add to the ARP table
mac	The MAC address to add to the ARP table
perm	If non-zero then add the entry to the ARP table as a static entry.

Returns

-1 on error or 0 on success

cnet_arp_delete()

CNDP_API int cnet_arp_delete

(

struct in_addr *

addr

)

Delete an ARP entry

Parameters

addr	The IP address to delete

Returns

0 on success or -1 on error

cnet_arp_show()

CNDP_API int cnet_arp_show

(

void

)

Show the stack entry ARP table, each stack has an ARP table

Returns

0 on success or -1 on error
