Detailed Description
AutoIP Automatic LinkLocal IP Configuration.
This is a AutoIP implementation for the lwIP TCP/IP stack. It aims to conform with RFC 3927.
Definition in file lwip_autoip.c.
Function Documentation
Sends an ARP announce from a network interface.
- Parameters:
-
netif network interface used to send the announce
Definition at line 216 of file lwip_autoip.c.
Sends an ARP probe from a network interface.
- Parameters:
-
netif network interface used to send the probe
Definition at line 203 of file lwip_autoip.c.
void autoip_arp_reply | ( | struct netif * | netif, |
struct etharp_hdr * | hdr | ||
) |
Handles every incoming ARP Packet, called by etharp_input().
- Parameters:
-
netif network interface to use for autoip processing hdr Incoming ARP packet
Definition at line 453 of file lwip_autoip.c.
Configure interface for use with current LL IP-Address.
- Parameters:
-
netif network interface to configure with current LL IP-Address
Definition at line 227 of file lwip_autoip.c.
static void autoip_create_addr | ( | struct netif * | netif, |
ip4_addr_t * | ipaddr | ||
) | [static] |
Create an IP-Address out of range 169.254.1.0 to 169.254.254.255.
- Parameters:
-
netif network interface on which create the IP-Address ipaddr ip address to initialize
Definition at line 168 of file lwip_autoip.c.
static void autoip_handle_arp_conflict | ( | struct netif * | netif ) | [static] |
Handle a IP address conflict after an ARP conflict detection.
Definition at line 135 of file lwip_autoip.c.
void autoip_network_changed | ( | struct netif * | netif ) |
Handle a possible change in the network configuration.
If there is an AutoIP address configured, take the interface down and begin probing with the same address.
Definition at line 332 of file lwip_autoip.c.
static void autoip_restart | ( | struct netif * | netif ) | [static] |
Restart AutoIP client and check the next address (conflict detected)
- Parameters:
-
netif The netif under AutoIP control
Definition at line 124 of file lwip_autoip.c.
u8_t autoip_supplied_address | ( | const struct netif * | netif ) |
check if AutoIP supplied netif->ip_addr
- Parameters:
-
netif the netif to check
- Returns:
- 1 if AutoIP supplied netif->ip_addr (state BOUND or ANNOUNCING), 0 otherwise
Definition at line 511 of file lwip_autoip.c.
void autoip_tmr | ( | void | ) |
Has to be called in loop every AUTOIP_TMR_INTERVAL milliseconds.
Definition at line 365 of file lwip_autoip.c.
