From a79878f00dad97d03a3e62a48b06227d55ae5fe4 Mon Sep 17 00:00:00 2001 From: "Denis V. Lunev" Date: Mon, 14 Jan 2008 22:56:01 -0800 Subject: [ARP]: Move inet_addr_type call after simple error checks in arp_contructor. The neighbour entry will be destroyed in the case of error, so it is pointless to perform constly routing table lookup in this case. Signed-off-by: Denis V. Lunev Signed-off-by: David S.
