From 9aa88c2a509e11e6efc466c88b386e0e01bef731 Mon Sep 17 00:00:00 2001 From: Allan Stephens Date: Tue, 31 May 2011 13:38:02 -0400 Subject: tipc: Enhance sending of bulk name table messages Modifies the initial transfer of name table entries to a new neighboring node so that the messages are enqueued as a unit, rather than individually. The revised algorithm now locates the link carrying the message only once, and eliminates unnecessary checks for link congestion, message fragmentation, and message bundling that are not required when sending these messages.
