Allan Stephens 50d3e6399a tipc: Correct misnamed references to neighbor discovery domain
Renames items that are improperly labelled as "network scope" items
(which are represented by simple integer values) rather than "network
domain" items (which are represented by <Z.C.N>-type network addresses).
This change is purely cosmetic, and does not affect the operation of TIPC.

Allan Stephens f831c963b5 tipc: Eliminate configuration for maximum number of cluster nodes
Gets rid of the need for users to specify the maximum number of
cluster nodes supported by TIPC. TIPC now automatically provides
support for all 4K nodes allowed by its addressing scheme.

Note: This change sets TIPC's memory usage to the amount used by
a maximum size node table with 4K entries.  An upcoming patch that
converts the node table from a linear array to a hash table will
compact the node table to a more efficient design, but for clarity
it is nice to have all the Kconfig infrastruture go away separately.

Allan Stephens 0e65967e33 tipc: cleanup various cosmetic whitespace issues
Cleans up TIPC's source code to eliminate deviations from generally
accepted coding conventions relating to leading/trailing white space
and white space around commas, braces, cases, and sizeof.

These changes are purely cosmetic and do not alter the operation of TIPC
in any way.

Simplifies routines and data structures that were intended to allow
TIPC to support slave nodes (i.e. nodes that did not have links to
all of the other nodes in its cluster, forcing TIPC to route messages
that it could not deliver directly through a non-slave node).

Currently, TIPC supports only networks containing non-slave nodes,
so this code is unnecessary.

Note: The latest edition of the TIPC 2.0 Specification has eliminated
the concept of slave nodes entirely.

Allan Stephens d265fef6dd tipc: Remove obsolete native API files and exports
As part of the removal of TIPC's native API support it is no longer
necessary for TIPC to export symbols for routines that can be called
by kernel-based applications, nor for it to have header files that
kernel-based applications can include to access the declarations for
those routines. This commit eliminates the exporting of symbols by
TIPC and migrates the contents of each obsolete native API include
file into its corresponding non-native API equivalent.

The code which was migrated in this commit was migrated intact, in
that there are no technical changes combined with the relocation.

Allan Stephens 03194379a7 tipc: Fix initialization sequence problems when entering network mode
This patch ensures that TIPC's topology service and configuration
service are shut down before switching into "network mode".  This
ensures that TIPC does not mistakenly try to send unnecessary
"publication withdraw" messages to other nodes before it is fully
initialized for sending off-node messages.  Note that the node's
current network address is now updated only after the two services
are shut down; this ensures that any existing connections to the
topology server are terminated correctly using the old address.

This patch prevents a TIPC configuration command requiring network

handling code avoids the use of a potentially uninitialized global
variable by transforming the unauthorized command into a new command,
then following the standard command processing path to generate the
required error message.

Arnaldo Carvalho de Melo 27a884dc3c [SK_BUFF]: Convert skb->tail to sk_buff_data_t
So that it is also an offset from skb->head, reduces its size from 8 to 4 bytes
on 64bit architectures, allowing us to combine the 4 bytes hole left by the
layer headers conversion, reducing struct sk_buff size to 256 bytes, i.e. 4
64byte cachelines, and since the sk_buff slab cache is SLAB_HWCACHE_ALIGN...
:-)

Many calculations that previously required that skb->{transport,network,
mac}_header be first converted to a pointer now can be done directly, being
meaningful as offsets or pointers.

	  echo "De-casting $f..."
	  perl -pi -e "s/ ?= ?\([^\)]*\) *(k[cmz]alloc) *\(/ = \1\(/" $f
	done

And then go through and reinstate those cases where code is casting pointers
to non-pointers.

And then drop a few hunks which conflicted with outstanding work.
