Subject: [ 24/73] ipv4: fix for ip_options_rcv_srr() daddr update.

3.0-stable review patch.  If anyone has any objections, please let me know.

------------------


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.
