This patch updates the error messages displayed in kernel log to include
hwaddress of the source machine that caused ipv6 duplicate address
detection failures.
Examples:
a) When we receive a NA packet from another machine advertising our
address:
ICMPv6: NA: 34:ab:cd:56:11:e8 advertised our address 2001:db8:: on eth0!
b) When we detect DAD failure during address assignment to an interface:
IPv6: eth0: IPv6 duplicate address 2001:db8:: used by 34:ab:cd:56:11:e8
detected!
v2:
Changed %pI6 to %pI6c in ndisc_recv_na()
Chaged the v6 address in the commit message to 2001:db8::
