From dd927a2694ee412b440284dd72dd8e32caada3fc Mon Sep 17 00:00:00 2001 From: "David S. Miller" Date: Wed, 4 May 2011 12:03:30 -0700 Subject: ipv4: In ip_build_and_send_pkt() use 'saddr' and 'daddr' args passed in. Instead of rt->rt_{dst,src} The only tricky part is source route option handling. If the source route option is enabled we can't just use plain 'daddr', we have to use opt->opt.faddr.
