Hi,

* I support using ECT(1) as an output signal from the network.

Having better feedback (more fine grained congestion signal)
from the network is really valuable in various contexts.
ECT(1) could be used as output for various different approaches,
not just L4S. I believe that a DSCP can be used as input signal
for L4S instead.

Regards,
 Roland
