I had a quick question about skbuff. In the skb, I understand that skb->len = skb->data - skb->tail. What is data_len field? Is this skb->data_len = skb-end - skb->data ? But, looking from the code, it looks like skb->len is always greater than skb->data_len! Your answer will be greatly appreciated.
