I think you want to know this !!!!
struct ifreq macif;
struct net_device *dev;
unsigned char * mac_ptr;
if ((dev = __dev_get_by_name("eth0")) == NULL)
return -ENODEV;
memcpy(macif.ifr_hwaddr.sa_data, dev->dev_addr, MAX_ADDR_LEN);
mac_ptr = macif.ifr_hwaddr.sa_data; // MAC Address
Please include necessary header files, I don't remember the names !!!!
