ip: set arp entry for own v6 address when not tentative
after running ip/ipconfig -6, we are unable to ping our
own link-local address and the arp daemon sends out useless
neighbor solicitation requests to itself. this change
adds an arp entry for our ipv6 address. however, this
must not be done for tentative interface configuration.
