I read the draft and had a clarification question about Section 1.3
and Section 4.

Is the draft suggestion an alternate congestion control mechanism
between tunnel ingress and tunnel egress which is working separately
from end-to-end congestion control that requires ECN?

If it's just about propagation of bits for the original feedback loop
(i.e. before the tunnel header is added), I support the draft.  If
it's attempting to define a new congestion feedback loop and
mechanism, I think it may need more discussion.

Thanks,
Anoop
