Hi,
I think you could use etharp_find_addr to read the ARP table :
s
/**
* Finds (stable) ethernet/IP address pair from ARP table
* using interface and IP address index.
* @note the addresses in the ARP table are in network order!
*
* @param netif points to interface index
* @param ipaddr points to the (network order) IP address index
* @param eth_ret points to return pointer
* @param ip_ret points to return pointer
* @return table index if found, -1 otherwise
*/
s8_t etharp_find_addr(struct netif *netif, struct ip_addr *ipaddr, struct
eth_addr **eth_ret, struct ip_addr **ip_ret);

Objet : [lwip-users] Source MAC address
Hi all,
My system uses non connected sockets (UDP) to get data from other
machines. Some packets are received thru broadcast address
(255.255.255.255).
In the thread wich manages the rx socket, I'd like to know the sender
MAC address. I allready have the sender IP address but that is not what
I want.
It seems it is not posible to get this information without a big
modification of lwip.
I am wrong ?
Nicolas
