Subject: [PATCH 1/4] IPaddr2: Allow to disable Duplicate Address Detection for
 IPv6

"Starting" an IPv6 address with IPaddr2 involves performing Duplicate
Address Detection which typically takes at least 1000 ms. Allow the user
to disable DAD if they can guarantee that the configured address is not
duplicate and they wish to start the resource faster.
