Detailed Description

Network link address library.

Macro Definition Documentation

NET_LINK_ADDR_MAX_LENGTH

#define NET_LINK_ADDR_MAX_LENGTH   6

#include <include/zephyr/net/net_linkaddr.h>

Maximum length of the link address.

Enumeration Type Documentation

net_link_type

enum net_link_type

#include <include/zephyr/net/net_linkaddr.h>

Type of the link address.

This indicates the network technology that this address is used in. Note that in order to save space we store the value into a uint8_t variable, so please do not introduce any values > 255 in this enum.

Enumerator
NET_LINK_UNKNOWN	Unknown link address type.
NET_LINK_IEEE802154	IEEE 802.15.4 link address.
NET_LINK_BLUETOOTH	Bluetooth IPSP link address.
NET_LINK_ETHERNET	Ethernet link address.
NET_LINK_DUMMY	Dummy link address. Used in testing apps and loopback support.
NET_LINK_CANBUS_RAW	CANBUS link address.

Function Documentation

net_linkaddr_cmp()

static bool net_linkaddr_cmp ( struct net_linkaddr *  lladdr1, struct net_linkaddr *  lladdr2  )

inlinestatic

#include <include/zephyr/net/net_linkaddr.h>

Compare two link layer addresses.

Parameters

lladdr1	Pointer to a link layer address
lladdr2	Pointer to a link layer address

Returns

True if the addresses are the same, false otherwise.

net_linkaddr_set()

static int net_linkaddr_set ( struct net_linkaddr_storage *  lladdr_store, uint8_t *  new_addr, uint8_t  new_len  )

inlinestatic

#include <include/zephyr/net/net_linkaddr.h>

Set the member data of a link layer address storage structure.

Parameters

lladdr_store	The link address storage structure to change.
new_addr	Array of bytes containing the link address.
new_len	Length of the link address array. This value should always be <= NET_LINK_ADDR_MAX_LENGTH.
