Ive been trying to get the hardware address from the sk_buff throughs skb->nh.arph->ar_sha, or kb->mac.ethernet->h_source. with the second one the code compiles, but i get an empty string. It would be really appreciated if someone could help me find my error in using these, or point me to a better way of getting the address.
