Date: Thu, 25 Jun 2020 22:18:00 +0200 From: Toke Høiland-Jørgensen <toke@...hat.com> To: David Miller <davem@...emloft.net> Cc: Kevin Darbyshire-Bryant <ldir@...byshire-bryant.me.uk>, netdev@...r.kernel.org, cake@...ts.bufferbloat.net, Toke Høiland-Jørgensen <toke@...hat.com> Subject: [PATCH RESEND net-next] sch_cake: add RFC 8622 LE PHB support to CAKE diffserv handling From: Kevin Darbyshire-Bryant <ldir@...byshire-bryant.me.uk> 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.
