Parameters:
netif network interface to configure with current LL IP-Address
Definition at line 252 of file autoip.c .
static void autoip_create_addr
(
struct netif *
netif ,
ip_addr_t *
ipaddr
)
[static]

Parameters:
netif network interface on which create the IP-Address
ipaddr ip address to initialize
Definition at line 193 of file autoip.c .
static void autoip_handle_arp_conflict
(
struct netif *
netif )
[static]
Handle a IP address conflict after an ARP conflict detection.
