[Ecn-sane] ect(1) queue selector question

[Dave Taht]

I note that I have done my best to stay out of this for a while, so
long that I (thankfully) mis-remember various aspects of the debate.
Today I have a question about l4s vs SCE as it's come up again.

l4s uses both a dscp codepoint AND ect(1) to indicate dctcp style
congestion control
is in use, and also can dump other protocols into that queue lacking
any ecn markings.

SCE proposes to use ect(1) as an indicator of some congestion and does
not explictly
require a dscp codepoint in a FQ'd implementation.

Do I have that right? Now, my question was, simply, in MPLS or X-G are
they out of bits, and
that's why they want to use up this one in L4S?
