Revises routines that deal with connections between two ports on
the same node to ensure the connection is not impacted if the node's
network address is changed in mid-operation. The routines now treat
the default node address of <0.0.0> as an alias for "this node" in
the following situations:

1) Incoming messages destined to a connected port now handle the alias
properly when validating that the message was sent by the expected
peer port, ensuring that the message will be accepted regardless of
whether it specifies the node's old network address or it's current one.

2) The code which completes connection establishment now handles the
alias properly when determining if the peer port is on the same node
as the connected port.

An added benefit of addressing issue 1) is that some peer port
validation code has been relocated to TIPC's socket subsystem, which
means that validation is no longer done twice when a message is
sent to a non-socket port (such as TIPC's configuration service or
network topology service).

Re-orders port creation logic so that the initialization of a new
port's message header template occurs while the port list lock is
held. This ensures that a change to the node's network address that
occurs at the same time as the port is being created does not result
in the template identifying the sender using the former network
address. The new approach guarantees that the new port's template is
using the current network address or that it will be updated when
the address changes.

Removes an unnecessary check in the logic that updates the message
header template for existing ports when a node's network address is
first assigned. There is no longer any need to check to see if the

own network cluster, and which work properly regardless of whether
the node is using the default network address <0.0.0> or a non-zero
network address that is assigned later on. In essence, these routines
ensure that address <0.0.0> is treated as an alias for "this node",
regardless of which network address the node is actually using.

Ensures that node-scope name publications that exist prior to the
configuration of a node's network address are properly re-initialized
with that address when it is assigned. TIPC's node-scope publications
are now tracked using a publications list like the lists used for
cluster-scope and zone-scope publications so they can be easily updated
when required.

The inclusion of node scope name publications in a conventional publication
list means that they must now also be withdrawn, just like cluster and zone
scope publications are currently withdrawn.  So some conditional tests on
scope ==/!= TIPC_NODE_SCOPE are inserted/removed accordingly.

Utilizes distinct lists to track zone-scope and cluster-scope names
published by a node. For now, TIPC continues to process the entries
in both lists in the same way; however, an upcoming patch will utilize
the existence of the lists to prevent the sending of cluster-scope names
to nodes that are not part of the local cluster.

To achieve this, an array of publication lists is introduced, so
that they can be iterated over and accessed via publ->scope as
an index where convenient.

There is currently a single list that is containing both cluster-scope and

variable.  Create a struct to bind the count to the list, and to pave
the way for factoring out the publications into zone/cluster/node scope.

The current "publ_root" most matches what will be the cluster scope
list, so it is named accordingly in this commit.

This adds FDB bridge ops to the macvlan device passthru mode.
Additionally a flags field was added and a NOPROMISC bit to
allow users to use passthru mode without the driver calling
dev_set_promiscuity(). The flags field is a u16 placed in a
4 byte hole (consuming 2 bytes) of the macvlan_dev struct.

We want to do this so that the macvlan driver or stack
above the macvlan driver does not have to process every
packet. For the use case where we know all the MAC addresses
of the endstations above us this works well.

This patch is a result of Roopa Prabhu's work. Follow up
patches are needed for VEPA and VEB macvlan modes.

v2: Change from distinct nopromisc mode to a flags field to
    configure this. This avoids the tendency to add a new
    mode every time we need some slightly different behavior.
v3: fix error in dev_set_promiscuity and add change and get
    link attributes for flags.

The UTA table was being set to the functional equivalent of promiscuous
mode.  This was resulting in traffic from the virtual function being
flooded onto the wire and the PF device. This resulted in additional
overhead for VF traffic sent to the network and in the case of traffic
sent to the PF or another VF resulted in unwanted packets on the wire.

This was actually not the intended behavior. Now that we can program
the embedded switch correctly we can remove this snippit of code. Users
who want to support this should configure the FDB correctly using the
FDB ops.
