This series introduces UDP replicast. A concept where we emulate multicast by sending multiple unicast messages to configured peers. This allows TIPC to be used in environments where IP multicast is disabled.
There is a corresponding patch series for the tipc user space tool that allows a user to add remote addresses to the replicast list.
