[PATCH 00/10 net-next v2] net/tipc: fix all kernel-doc and add TIPC networking chapter

[Randy Dunlap]

Fix lots of net/tipc/ kernel-doc warnings. Add many struct field and
function parameter descriptions.

Then add a TIPC chapter to the networking documentation book.

All patches have been rebased to current net-next.


Note: some of the struct members and function parameters are marked
with "FIXME". They could use some additional descriptions if
someone could help add to them. Thanks.

[PATCH 01/10 net-next v2] net/tipc: fix tipc header files for kernel-doc

[Randy Dunlap]

Fix tipc header files for adding to the networking docbook.

Remove some uses of "/**" that were not kernel-doc notation.

Fix some source formatting to eliminate Sphinx warnings.

Add missing struct member and function argument kernel-doc descriptions.

Correct the description of a couple of struct members that were
marked as "(FIXME)".

[PATCH 09/10 net-next v2] net/tipc: fix all function Return: notation

[Randy Dunlap]

Fix Return: kernel-doc notation in all net/tipc/ source files.
Also keep ReST list notation intact for output formatting.
Fix a few typos in comments.
