[tipc-discussion] [PATCH net-next v2 0/6] Introduce new TIPC server module

[Ying X. <yin...@wi...>]

Jon and Erik,

Comparing with last version, the following changes have been made:

 - Add necessary descriptions for new defined structures and
   functions by Erik's comments;
 - Update the header of the first patch header by Erik's suggestion;
 - Enhance allocation of connection ID to avoid possible duplication;
 - Make server support connectionless connection;
 - Convert configuration server with the interface of new server;
 - Remove implementation associated with user port;
 - Convert config_lock to mutex lock

Until now all native user port code is purged completely. Therefor,
after this time, I believe, TIPC stack code becomes more clean and
more understandable.

I have tested them with tipcTS&tipcTC as well as test cases in
tipcutils package for a while, and no any exception happens.

So please review them again.

Lastly I appreciate Erik to give me valuable suggestions and find
some potential problems.

PS. Based on this series, I have implemented a prototype to remove
port lock and aggregate tipc_port structure as a field inside
tipc_sock, however, it's still unstable due to some unknown reasons.
Once they are settled down, I will submit them in next step.
