Chia-Yu Chang says:
====================
DUALPI2 patch
This patch serise adds DualPI Improved with a Square (DualPI2) with
following features:
* Supports congestion controls that comply with the Prague requirements
in RFC9331 (e.g. TCP-Prague)
* Coupled dual-queue that separates the L4S traffic in a low latency
queue (L-queue), without harming remaining traffic that is scheduled
in classic queue (C-queue) due to congestion-coupling using PI2
as defined in RFC9332
* Configurable overload strategies
* Use of sojourn time to reliably estimate queue delay
* Supports ECN L4S-identifier (IP.ECN==0b*1) to classify traffic into
respective queues
For more details of DualPI2, please refer IETF RFC9332
(https://datatracker.ietf.org/doc/html/rfc9332).
