net: add _skb_dst opaque field
struct sk_buff uses one union to define dst and rtable fields. We want to replace direct access to these pointers by accessors. First patch adds a new "unsigned long _skb_dst;" opaque field in this union. Signed-off-by: Eric Dumazet <eric.dumazet@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
