 I recently changed our network stack to support IN_IFF_TENTATIVE and
 friends in a similar vein to IN6_IFF_TENTATIVE which have been around
 for a very long time.
 I also made a change a while ago that when the link state goes DOWN, all
 addresses are marked as IN{,6}_IFF_DETATCHED and when it goes UP all
 addresses marked are marked as IN{,6}_IFF_TENTATIVE and the resptive DAD
 process happens.
 For INET, ARP reqests are resent and when valid, the gratuitous ARP is
 sent. This sequence of fixes should address this PR which I stumbled
 upon by accident today. A current kernel from mid May 2015 should have
 all the fixes needed to test with.
