tipc: rename struct link* to struct tipc_link*

2011-12-30T02:53:30+00:00

This converts the following:

	struct link		->	struct tipc_link
	struct link_req		->	struct tipc_link_req
	struct link_name	->	struct tipc_link_name

tipc: rename struct bcbearer* to tipc_bcbearer*

2011-12-30T02:53:30+00:00

This changes both the struct bcbearer and struct bcbearer_pair to
have the "tipc_" prefix.  Runtime behaviour is unchanged.

tipc: rename struct bclink to struct tipc_bclink

2011-12-30T02:53:30+00:00

Make this rename so that it is consistent with the majority
of the other tipc structs and to assist in removing any
ambiguity with other similar names in other subsystems.

tipc: rename struct port_list to struct tipc_port_list

2011-12-30T02:53:29+00:00

Make this rename so that it is consistent with the majority
of the other tipc structs and to assist in removing any
ambiguity with other similar names in other subsystems.

tipc: rename struct media to struct tipc_media

2011-12-30T02:53:29+00:00

Give it a meaningful prefix, as suggested by DaveM, so that it
is consistent with things like struct tipc_bearer, and so it isn't
confused with anything else.  This has no impact on the actual
runtime code behaviour.

tipc: Allow use of buf_seqno() helper routine by unicast links

2011-12-27T16:33:54+00:00

Migrates the buf_seqno() helper routine from broadcast link level to
unicast link level so that it can be used both types of TIPC links.
This is a cosmetic change only, and does not affect the operation of TIPC.

tipc: Ignore broadcast acknowledgements that are out-of-range

2011-12-27T16:33:53+00:00

Adds checks to TIPC's broadcast link so that it ignores any
acknowledgement message containing a sequence number that does not
correspond to an unacknowledged message currently in the broadcast
link's transmit queue.

This change prevents the broadcast link from becoming stalled if a
newly booted node receives stale broadcast link acknowledgement
information from another node that has not yet fully synchronized
its end of the broadcast link to reflect the current state of the
new node's end.

tipc: Flush unsent broadcast messages when contact with last node is lost

2011-12-27T16:33:52+00:00

Adds code to release any unsent broadcast messages in the broadcast link
transmit queue if TIPC loses contact with its only neighboring node.
Previously, a broadcast link that was in the congested state would hold
on to the unsent messages, even though the messages were now undeliverable.

tipc: Minor optimization of broadcast link transmit queue statistic

2011-12-27T16:33:51+00:00

The two broadcast link statistics fields that are used to derive the
average length of that link's transmit queue are now updated only after
a successful attempt to send a broadcast message, since there is no need
to update these values when an unsuccessful send attempt leaves the
queue unchanged.

tipc: Handle broadcast attempt when no neighboring nodes exist

2011-12-27T16:33:50+00:00

Adds a check to detect when an attempt is made to send a message
via the broadcast link and no neighboring nodes are currently available
to receive it. Rather than wasting effort passing the message to the
broadcast link and broadcast bearer, who will only throw it away,
TIPC now frees the message immediately and reports success (i.e. the
message has been delivered to all available destinations).
