From: Allan Stephens Date: Tue, 25 Jan 2011 21:12:39 +0000 (-0500) Subject: tipc: Avoid reliable broadcast preparation for NACK messages X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=bf781ecfc6d6ecc4f66762a870f9c1fc76b9c8d5;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git tipc: Avoid reliable broadcast preparation for NACK messages Enhance TIPC to skip unnecessary (and, in some cases, redundant) preparation work when sending a broadcast link NACK message, since this preparation is only required for broadcast messages that are sent in a reliable manner. This change also fixes a bug that caused NACK messages to be improperly counted as "TX packets" in TIPC's broadcast link statistics.
