From c30883bdff0b3544900a5c4aba18b8985436878f Mon Sep 17 00:00:00 2001 From: "David S. Miller" Date: Thu, 12 May 2011 19:30:58 -0400 Subject: ipv4: Simplify iph->daddr overwrite in ip_options_rcv_srr(). We already copy the 4-byte nexthop from the options block into local variable "nexthop" for the route lookup. Re-use that variable instead of memcpy()'ing again when assigning to iph->daddr after the route lookup succeeds. Signed-off-by: David S.
