From b8392808eb3fc28e523e28cb258c81ca246deb9b Mon Sep 17 00:00:00 2001 From: Kevin Darbyshire-Bryant Date: Thu, 25 Jun 2020 22:18:00 +0200 Subject: [PATCH] sch_cake: add RFC 8622 LE PHB support to CAKE diffserv handling MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Change tin mapping on diffserv3, 4 & 8 for LE PHB support, in essence making LE a member of the Bulk tin. Bulk has the least priority and minimum of 1/16th total bandwidth in the face of higher priority traffic. NB: Diffserv 3 & 4 swap tin 0 & 1 priorities from the default order as found in diffserv8, in case anyone is wondering why it looks a bit odd.
