Subject: ipv6: Log the explicit address that triggered DAD failure
X-Git-Tag: v2.6.32-rc1~703^2~380
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=a6fa32866567351503db8a5c3466a676ba08595f;p=karo-tx-linux.git

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.
