tcp: unalias tcp_skb_cb flags and ip_dsfield
struct tcp_skb_cb contains a "flags" field containing either tcp flags or IP dsfield depending on context (input or output path) Introduce ip_dsfield to make the difference clear and ease maintenance. If later we want to save space, we can union flags/ip_dsfield Signed-off-by: Eric Dumazet <eric.dumazet@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
