[Cake] https://tools.ietf.org/html/draft-ietf-tsvwg-le-phb-06 is in last call

[Dave Taht <dave.taht@gmail.com>]

And seems likely to be adopted.

There seems to be an urge to make this codepoint starvable, which
since I ascribe to nagle's dictum "every application has a right to
one packet in the network" - doesn't work for me - but the draft is
vaguely worded enough to just start dumping this codepoint into the
background queue of both sqm and cake and worry about it in a decade
or three.

it's 000001 which I guess is:

diff --git a/sch_cake.c b/sch_cake.c
index 3a26db0..67263b3 100644

(or is that reversed? my big endian/little endian chops scuks, and
nobody modified the gen_cake_const tool to match what cake expects
now)

on my off days I kind of wish the diffserv lookup we do in cake had
managed to make it into the linux mqprio/prio stuff by default.
