Subject: [PATCH 3/13 net-3.1-stable] ipv4: fix for ip_options_rcv_srr()
 daddr update.

From: Li Wei <lw@...fujitsu.com>

[ Upstream commit b12f62efb8ec0b9523bdb6c2d412c07193086de9 ]

When opt->srr_is_hit is set skb_rtable(skb) has been updated for
'nexthop' and iph->daddr should always equals to skb_rtable->rt_dst
holds, We need update iph->daddr either.
