Hello. skb_push function extends the used data area of the buffer at the buffer start.
It substracts skb->data by len - this is right, because we extends data space at the start. But why this function adds skb->len by len, not skb->data_len? I think that total size of our buffer is the same - header substracts by len at the end and data adds by len at the stast. Am I wrong? Best regards, Igor Ryzhov
