net: add skb_[inner_]tcp_all_headers helpers
Most drivers use "skb_transport_offset(skb) + tcp_hdrlen(skb)" to compute headers length for a TCP packet, but others use more convoluted (but equivalent) ways. Add skb_tcp_all_headers() and skb_inner_tcp_all_headers() helpers to harmonize this a bit. Signed-off-by: Eric Dumazet <edumazet@google.com> Signed-off-by: David S. Miller <davem@davemloft.net>
