net: adopt skb_network_offset() and similar helpers
This is a cleanup patch, making code a bit more concise. 1) Use skb_network_offset(skb) in place of (skb_network_header(skb) - skb->data) 2) Use -skb_network_offset(skb) in place of (skb->data - skb_network_header(skb)) 3) Use skb_transport_offset(skb) in place of (skb_transport_header(skb) - skb->data) 4) Use skb_inner_transport_offset(skb) in place of (skb_inner_transport_header(skb) - skb->data) Signed-off-by: Eric Dumazet <edumazet@google.com> Acked-by: Edward Cree <ecree.xilinx@gmail.com> # for sfc Signed-off-by: David S. Miller <davem@davemloft.net>
