[IPV6] ADDRCONF: Optimistic Duplicate Address Detection (RFC 4429) Support.
Nominally an autoconfigured IPv6 address is added to an interface in the
Tentative state (as per RFC 2462). Addresses in this state remain in this
state while the Duplicate Address Detection process operates on them to
determine their uniqueness on the network. During this period, these
tentative addresses may not be used for communication, increasing the time
before a node may be able to communicate on a network. Using Optimistic
Duplicate Address Detection, autoconfigured addresses may be used
immediately for communication on the network, as long as certain rules are
followed to avoid conflicts with other nodes during the Duplicate Address
Detection process.
