Date: Tue, 15 Jan 2013 12:47:35 +0800 From: Harvey Yang <harvey.huawei.yang@...il.com> To: "David S. Miller" <davem@...emloft.net>, Alexey Kuznetsov <kuznet@....inr.ac.ru>, James Morris <jmorris@...ei.org>, Hideaki YOSHIFUJI <yoshfuji@...ux-ipv6.org> Cc: netdev@...r.kernel.org, linux-kernel@...r.kernel.org, Harvey Yang <harvey.huawei.yang@...il.com> Subject: [PATCH 1/1] net: ipv4: refine the logic for determining daddr in ip_queue_xmit. The destination address daddr is faddr if source route option is set, otherwise it is inet_daddr. So use if-else to assign the value.
