/* code snippent */
 char src[ETH_ALEN+2];
 char dst[ETH_ALEN+2];

 eth_header = eth_hdr(skb);
 memcpy(src , eth_header->h_source , ETH_ALEN );
 memcpy(dst , eth_header->h_dest , ETH_ALEN );


Linux crashes . But if comment out memcpy lines  . It works . What is
the problem here ?
How can i printk both source mac and dest mac address  ?

Thanks,
Ratheesh
