[IPV4]: Add 'rtable' field in struct sk_buff to alias 'dst' and avoid casts
(Anonymous) unions can help us to avoid ugly casts. A common cast it the (struct rtable *)skb->dst one. Defining an union like : union { struct dst_entry *dst; struct rtable *rtable; }; permits to use skb->rtable in place. Signed-off-by: Eric Dumazet <dada1@cosmosbay.com> Signed-off-by: David S.
