V6 changes:
 - removed ability to fill the list of macaddr per link to fix the
   issue of netlink skb size. This can be added back by using separate
   netlink dumper in kernel and parse inside iproute2 codes. Those codes
   are beyond my abilities so if anyone actually need that feel free to 
   help.

I'm not applying this patch until you add an appropriate way to query
the setting, working around the link dump SKB size issue by not providing
a way to query the information at all is not acceptable.
