AutoIP Automatic LinkLocal IP Configuration
This is a AutoIP implementation for the lwIP TCP/IP stack. It aims to conform with RFC 3927.
| #define LWIP_AUTOIP_CREATE_SEED_ADDR | ( | netif | ) |
Macro that generates the initial IP address to be tried by AUTOIP. If you want to override this, define it to something else in lwipopts.h.
| #define LWIP_AUTOIP_RAND | ( | netif | ) |
Pseudo random macro based on netif informations. You could use "rand()" from the C Library if you define LWIP_AUTOIP_RAND in lwipopts.h
| void autoip_arp_reply | ( | struct netif * | netif, |
| struct etharp_hdr * | hdr | ||
| ) |
Handles every incoming ARP Packet, called by etharp_input().
| netif | network interface to use for autoip processing |
| hdr | Incoming ARP packet |
| 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.
| u8_t autoip_supplied_address | ( | const struct netif * | netif | ) |
| void autoip_tmr | ( | void | ) |
Has to be called in loop every AUTOIP_TMR_INTERVAL milliseconds
