From a6fa32866567351503db8a5c3466a676ba08595f Mon Sep 17 00:00:00 2001 From: Jens Rosenboom Date: Wed, 12 Aug 2009 22:16:04 +0000 Subject: [PATCH] ipv6: Log the explicit address that triggered DAD failure If an interface has multiple addresses, the current message for DAD failure isn't really helpful, so this patch adds the address itself to the printk.
