net: display hw address of source machine during ipv6 DAD failure
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::
