Subject: [PATCH] sch_cake: add RFC 8622 LE PHB support to CAKE diffserv
|
|
handling

MIME-Version: 1.0

|
|
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.
