From 7ffbcecbeed91e5874e9a1cfc4c0cbb07dac3069 Mon Sep 17 00:00:00 2001 From: David Miller Date: Tue, 27 Dec 2011 09:53:05 +0000 Subject: [PATCH] ipv6: Remove optimistic DAD flag test in ipv6_add_addr() The route we have here is for the address being added to the interface, ie. for input packet processing. Therefore using that route to determine whether an output nexthop gateway is known and resolved doesn't make any sense. So, simply remove this test, it never triggered anyways.
