[PATCH net-next 0/2] net/sched: implement L4S style ce_threshold_ect1 marking

From: Eric Dumazet <edumazet@google.com>

As suggested by Ingemar Johansson, Neal Cardwell, and others, fq_codel can be used
for Low Latency, Low Loss, Scalable Throughput (L4S) with a small change.

In ce_threshold_ect1 mode, only ECT(1) packets can be marked to CE if
their sojourn time is above the threshold.
