From ee6b967301b4aa5d4a4b61e2f682f086266db9fb Mon Sep 17 00:00:00 2001 From: Eric Dumazet Date: Wed, 5 Mar 2008 18:30:47 -0800 Subject: [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.
