Now it looks good to me.
For the whole series:

This series does some preparation and introduces UDP replicast. A concept
where we emulate multicast by sending multiple unicast messages to
configured peers. This is required for TIPC to work in environments where
IP multicast is disabled.
There is a corresponding patch series for the tipc user s
This patch introduces UDP replicast. A concept where we emulate
multicast by sending multiple unicast messages to configured peers.
The purpose of replicast is mainly to be able to use TIPC in cloud
environments where IP multicast is disabled. Using replicas to unicast
multicast messages is costly
Add a function to check if a tipc UDP media address is a multicast
address or not. This is a purely cosmetic change.

When using replicast a UDP bearer can have an arbitrary amount of
remote ip addresses associated with it. This means we cannot simply
add all remote ip addresses to an existing bearer data message as it
might fill the message, leaving us with a truncated message that we
can't safely resume. To hand
Split the UDP netlink parse function so that it only parses one
netlink attribute at the time. This makes the parse function more
generic and allow future UDP API functions to use it for parsing.

Split the UDP send function into two. One callback that prepares the
skb and one transmit function that sends the skb. This will come in
handy in later patches, when we introduce UDP replicast.

Automatically learn UDP remote IP addresses of communicating peers by
looking at the source IP address of incoming TIPC link configuration
messages (neighbor discovery).
This makes configuration slightly easier and removes the problematic
scenario where a node receives directly addressed neighbor
Add UDP bearer options to netlink bearer get message. This is used by
the tipc user space tool to display UDP options.
The UDP bearer information is passed using either a sockaddr_in or
sockaddr_in6 structs. This means the user space receiver should
intermediately store the retrieved data in a lar
