   4 Subject: [PATCH] sch_cake: add RFC 8622 LE PHB support to CAKE diffserv
   5  handling
   6 MIME-Version: 1.0
   7 Content-Type: text/plain; charset=UTF-8
   8 Content-Transfer-Encoding: 8bit
   9
  10 Change tin mapping on diffserv3, 4 & 8 for LE PHB support, in essence
  11 making LE a member of the Bulk tin.
  12
  13 Bulk has the least priority and minimum of 1/16th total bandwidth in the
  14 face of higher priority traffic.
  15
  16 NB: Diffserv 3 & 4 swap tin 0 & 1 priorities from the default order as
  17 found in diffserv8, in case anyone is wondering why it looks a bit odd.
