Add InfiniBand media type based on the ethernet media type.

The only real difference is that in case of InfiniBand, we need the entire
20 bytes of space reserved for media addresses, so the TIPC media type ID is
not explicitly stored in the packet payload.

There used to be a time when TIPC had lots of Kconfig knobs the
end user could alter, but they have all been made automatic or
obsolete, with the exception of CONFIG_TIPC_PORTS.  This
previously existing set of options was all hidden under the
TIPC_ADVANCED setting, which does not exist in any code, but
only in Kconfig scope.

Having this now, just to hide the one remaining "advanced"
option no longer makes sense.  Remove it.  Also get rid of the
ifdeffery in the TIPC code that allowed for TIPC_PORTS to be
possibly undefined.

Removes all references to the global variable that records whether
TIPC is running in "single node" mode or "network" mode, since this

records TIPC's network address. (i.e. a non-zero network address

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

ensures that TIPC does not mistakenly try to send unnecessary
"publication withdraw" messages to other nodes before it is fully

current network address is now updated only after the two services
are shut down; this ensures that any existing connections to the

This patch modifies TIPC's network topology service so that it
only requires a single reference table entry per subscriber
connection, rather than two.  This is achieved by letting the
reference to the server port communicating with the subscriber
act as the reference to the subscriber object itself.  (Since
the subscriber cannot exist without its port, and vice versa,
this dual role for the reference is perfectly natural.)  This
consolidation reduces the size of the reference table by 50%
in the default configuration.
