From 9157bafb44637a2cfefc222d6551100ead40e79e Mon Sep 17 00:00:00 2001 From: Allan Stephens Date: Mon, 24 Oct 2011 13:27:31 -0400 Subject: tipc: Minor optimization of broadcast link transmit queue statistic 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.
